:00:00. > :00:00.Channel. That is it from me. Now time for the news where you are
:00:00. > :00:23.Good night. Good evening. A police investigation
:00:24. > :00:28.is under way after more than 1, 00 people attended an illegal rave at a
:00:29. > :00:31.former Royal Mail delivery office in East Croydon. Nine people have been
:00:32. > :00:35.arrested and four were taken to hospital. Missiles including
:00:36. > :00:40.furniture and fire extinguishers were thrown at police when they
:00:41. > :00:45.arrived to shut the rave down. Damage left behind in central
:00:46. > :00:50.Croydon, by an unlicensed party in a disused sorting office. More than
:00:51. > :00:55.1,000 people are thought to have turned up. It continued for most of
:00:56. > :00:59.the night. A local resident filmed the scene.
:01:00. > :01:08.You can see people inside and hear the noise of the sound systems.
:01:09. > :01:14.One neighbour feared it might be the start of a riot. Hundreds and
:01:15. > :01:18.hundreds of people running around this street. I was a bit concerned
:01:19. > :01:24.they might start to damage the property. Then I could hear a lot of
:01:25. > :01:28.helicopters. The police vans had flashing lights. Police say officers
:01:29. > :01:34.entered the building at around . 30pm and several hours later people
:01:35. > :01:40.were still leaving. This pair didn't want to talk to us about the event.
:01:41. > :01:46.Why come here? Can you talk to us about what happened? The disruption
:01:47. > :01:51.shut down a section of the tram system. A local MP wants to know why
:01:52. > :01:54.the police didn't move in sooner. There'll be real questions to be
:01:55. > :01:58.asked about that. About intelligence. Did we know this would
:01:59. > :02:03.take place? And whether the police did everything they could to get
:02:04. > :02:07.enough resources here. Police say further arrests are likely in the
:02:08. > :02:11.coming days as a result of serious disorder in this area. A number of
:02:12. > :02:16.people in the crowd became violent. Objects were thrown at police and
:02:17. > :02:25.the window of a police vehicle wases will smashed. Six people were taken
:02:26. > :02:34.to hospital. Two had head injuries. 30 people have been unable to return
:02:35. > :02:37.home after a fire spread through flats in Chelmsford.
:02:38. > :02:43.Several people have been left homeless. One neighbour had to kick
:02:44. > :02:48.down doors to rescue others. An investigation is under way. City
:02:49. > :02:52.Hall has put forward proposals for record level of investment in
:02:53. > :02:55.flashing schemes. The proposals to be considered by the Environment
:02:56. > :03:00.Agency over the summer, include a range of projects in high-risk areas
:03:01. > :03:05.across the country. -- across the capital.
:03:06. > :03:10.Jim Wheble has looked at a project in Southwark.
:03:11. > :03:17.Surface water flooding around bricks on the and Herne Hill in -- Brixton
:03:18. > :03:23.and Herne Hill in 2004. To prevent this happening again, a few miles
:03:24. > :03:28.away in Dulwich park, a ?3.5 million project is under way. In recent
:03:29. > :03:31.years there have been more incidents of surface flooding. People are
:03:32. > :03:36.starting to realise we need to do more about this.
:03:37. > :03:40.So, you can see where the water is gathering now, in what is a
:03:41. > :03:45.representation of Dulwich park. The problem is our Victorian drains
:03:46. > :03:50.cannot cope with intense and heavy rainfall. Add to that another man
:03:51. > :03:54.made issue and you have a recipe for surface water flooding. As London
:03:55. > :04:00.has become more densely pop lated afternooned more our -- populated
:04:01. > :04:03.and more urbanised, we have lost surfaces all over London and there
:04:04. > :04:10.is less opportunity for the water to escape. Using underwater storage
:04:11. > :04:16.tanks, thanks to this project Herne Hill will be able to cope with a one
:04:17. > :04:22.in a 75-year weather event. There have been a number of plans
:04:23. > :04:26.proposed across the capital. We are looking how to re-enforce those
:04:27. > :04:31.programmes and have more drainage schemes brought across the capital
:04:32. > :04:36.to manage that risk of surface water flooding. This project in Dulwich
:04:37. > :04:40.park is due to finish next year These type of scenes in this area
:04:41. > :04:44.should become a thing of the past. The hope is money can be found so
:04:45. > :04:48.other places will be just as protected.
:04:49. > :04:53.A quick look at tomorrow's weather. A mostly dry and bright day, with
:04:54. > :04:58.some sunny spells. It will feel warm. A top temperature of 20
:04:59. > :05:05.Celsius. That's it. We will back tomorrow morning. For now, goodbye.
:05:06. > :05:13.Good evening. When the sunshine is out this week it should feel warm.
:05:14. > :05:18.The sun will have to fight through the cloud every now and again. With
