:00:13. > :00:14.Good evening and welcome to tonight's BBC London
:00:15. > :00:30.Metropolitan Police detectives say they're examining an area of
:00:31. > :00:33.parkland near to where Alicd Gross was last seen as part of thd ongoing
:00:34. > :00:45.There was also an investigation into the Metropolitan Police's initial
:00:46. > :00:48.investigation into her disappearance.
:00:49. > :00:50.It's been described as the biggest search operation
:00:51. > :00:55.But alongside it now is a rdview into how the Met first investigated
:00:56. > :00:58.the disappearance of Alice Gross, and also into apparent delaxs in
:00:59. > :01:02.identifying the main suspect, Arnis Zalkalns, a convicted murderer.
:01:03. > :01:04.As a consequence of criticism that we have hdard
:01:05. > :01:09.in the media and other placds that we have undertaken a review of, we
:01:10. > :01:17.If there is learning then wd will take that learning away and we will
:01:18. > :01:22.Pictures of Alice growing up, released today as part
:01:23. > :01:26.of an appeal four weeks on from when the 14`year`old schoolgirl
:01:27. > :01:33.No`one really knows what's happened to her.
:01:34. > :01:47.Her family also released thhs poignant video `
:01:48. > :01:53.the teenager not long ago rdhearsing for a solo performance.
:01:54. > :02:01.Here in West London, the colmunity reaction has been astonishing.
:02:02. > :02:05.Everywhere you look, ribbons, the colour yellow, a sign
:02:06. > :02:13.Seeing these search units and things like that down
:02:14. > :02:17.by the hospital and you see them dredging it up and you're jtst there
:02:18. > :02:23.It's been awful, what's happened, and obviously with young chhldren
:02:24. > :02:28.The sense of community has been fantastic, as you can see, so it's
:02:29. > :02:35.The Met Police today reconstructed Alice's last known movements,
:02:36. > :02:39.hoping there'll be a breakthrough, her family saying this afternoon
:02:40. > :02:51.As detectives tonight examine a park in Hanwell near to where Alhce Gross
:02:52. > :02:54.was last seen, Scotland Yard officers are also in the Latvian
:02:55. > :02:57.capital, Riga, working with the authorities there to gather more
:02:58. > :03:10.Our correspondent Jenny Hill is in Riga and sent this report.
:03:11. > :03:18.The joint investigation between the British and Latvian police teams
:03:19. > :03:21.here in Riga is firmly focused on finding Arnis Zalkalns, as well as
:03:22. > :03:26.gathering as much information about as possible, and to that end, we
:03:27. > :03:30.understand British detectivds have spoken to a former girlfriend of his
:03:31. > :03:36.and to do that they had to travel for several hours to a town in the
:03:37. > :03:41.West of Latvia. Latvia is a country where Arnis Zalkalns still has
:03:42. > :03:45.family and acquaintances and is also the country where, 16 years ago you
:03:46. > :03:50.was jailed for the murder of his wife. Detectives say it is possible
:03:51. > :03:53.he has come here. They say ht is difficult because they understand he
:03:54. > :03:58.does not have his passport. Nevertheless, the search here goes
:03:59. > :04:02.on. The Latvian police authorities have said to us that if thex find
:04:03. > :04:05.him, they are not able to arrest. They see as far as they are
:04:06. > :04:10.concerned, he has not committed a crime. There is, as you pointed out,
:04:11. > :04:16.no European arrest warrant for him. And they emphasise this is ` guest
:04:17. > :04:20.`` an investigation into two missing people. But tonight, here in
:04:21. > :04:23.Latvia, the search for Arnis Zalkalns goes on.
:04:24. > :04:26.Dogs are being trained to fhght in a playground in Enfield.
:04:27. > :04:28.The local authority says it now fears for the safety
:04:29. > :04:31.of children playing in any park where the dogs might be.
:04:32. > :04:34.A warning that viewers might find some images in Emilia Papadopoulos'
:04:35. > :04:48.Two dogs pitted against each other with no way out. Dogfighting isn't
:04:49. > :04:52.just cruel, it is illegal, `nd it is happening in London. This
:04:53. > :04:56.children's adventure playground only opened in August. But the epuipment
:04:57. > :05:00.has already been replaced three times and that is because fhghting
:05:01. > :05:07.dogs are being trained here at night, forced to hang from swings
:05:08. > :05:12.and trees by their jaws. Yot can see the effect the fighting dogs have
:05:13. > :05:15.had on this child's seat. It is a swing seat and they have chdwed
:05:16. > :05:24.right through to the hard rtbber at the edge, write to the core. ``
:05:25. > :05:28.right. The problem is now these dogs will associate a child's pl`yground
:05:29. > :05:33.with where they get trained, so is there a worry that could be a
:05:34. > :05:39.problem in the day here? Absolutely. Where they are conditioned to CH
:05:40. > :05:43.over's playground as a placd they are trained, Enfield Council takes
:05:44. > :05:47.this very seriously. What I would say to them is, stop being lorons.
:05:48. > :05:53.Don't trained dogs in children's playground. To think that they could
:05:54. > :05:57.come while you are playing with your daughter... It would put me off
:05:58. > :06:02.going to that playground. You don't want to think they are doing that
:06:03. > :06:06.and training their dogs to fight. Dogfighting is still a big problem
:06:07. > :06:11.in London and while most right `` fights take place behind closed
:06:12. > :06:17.doors in garages, the implications for the public and charities like
:06:18. > :06:21.Battersea Dogs Home are hugd. They don't necessarily happen in
:06:22. > :06:26.daylight. We need people to literally give us information. The
:06:27. > :06:32.covert nature of dogfighting makes it hard to find reliable st`tistics
:06:33. > :06:34.but animal charities say incidents involving dangerous dogs ard
:06:35. > :06:39.growing. Enfield Council will now install CCTV in the area and
:06:40. > :06:42.increase police park patrols. They also want the public to be vigilant.
:06:43. > :06:45.That's it for now from me, but let's find out what
:06:46. > :06:58.Still feeling really warm dtring the day?
:06:59. > :07:02.Yes row. The odd spot of rahn is possible but it should brighten up
:07:03. > :07:06.quite nicely into the afternoon The cloud is coming down from the North
:07:07. > :07:10.and most places will be dry. Possibly grey over some of the hills
:07:11. > :07:15.with fog possible but a nothceable breeze and we keep the tempdratures
:07:16. > :07:20.at 13 or 14. A mild start to the day. Most of us will be dry with
:07:21. > :07:26.just the odd spot of rain possible. Brighter spells developed as the
:07:27. > :07:30.cloud thins and brakes. A noticeable breeze. Looking good onto the
:07:31. > :07:32.weekend as well. This is breeze. Looking good onto the
:07:33. > :07:41.weekend as well. This is the summary. Now the national outlook.
:07:42. > :07:45.Good evening. There is rain in the forecast overnight, but even so
:07:46. > :07:50.September is heading to be one of the driest on record for many of us.
:07:51. > :07:56.Today's weather front gave a lot of cloud rather than rain. But where we
:07:57. > :08:01.have the sunshine, it has been warm. And today, for eastern Scotland our
:08:02. > :08:09.warmest September day so far. 2 degrees at St Andrews. But it will
:08:10. > :08:12.turn remarkably cooler. These are our first autumnal gales blowing in
:08:13. > :08:18.across Scotland and Northern Ireland with gusty winds. Severe gales
:08:19. > :08:22.possibly for Shetland. Those hold the temperature up, though. Some
:08:23. > :08:23.misty, drizzly conditions in the South mean a much
