BBC News with Sue Montgomery

There have been further

disturbance

s in parts of Britain after the unprecedented wave of rioting and looting that brought chaos to several cities on Monday night. Several hundred youths are reported to have clashed with riot police in central Manchester, where a large store has been set on fire. A short while ago, the BBC correspondent there, Arif Ansari, gave us details about the clashes.

I'm currently at Piccadilly, which is the main street through Manchester city centre. There are running battles going on now between the police and around two dozen young men and women - youths, teenagers - under the age of 20. The police are running after them. I see one young man who is seriously injured on the floor. There's no ambulance here, but there are just police who are walking past, and he seems to be very hurt.

There have also been a number of incidents in the Birmingham area, where youths broke shop windows and set fire to cars. The police have greatly increased their presence on the streets following Monday night's trouble. The decision came after a high-level security meeting chaired by the Prime Minister David Cameron. Here's our political correspondent Norman Smith.

The option of adopting a more

aggressive

continental approach with the use of curfews, water cannon and even rubber bullets has for now been rejected. Instead, there will be a massive increase in police numbers with 16,000 officers on the capital's streets. There will also be a much more aggressive approach towards arresting troublemakers and a fast-track judicial process to ensure those arrested appear in court within hours.
