A 26-year-old man became the first fatality of the UK riots after he was shot in a car in Croydon, south of London, police said on Tuesday, according to Reuters.

Additional details weren't immediately available.

British Prime Minister David Cameron will deploy 16,000 police officers on Tuesday to help get a handle on the riots, which have moved out of poor London neighborhoods to the wealthier cities of Liverpool and Birmingham.

Cameron cut short a vacation in Italy to return to London where he held an emergency parliamentary session on Tuesday and announced that 10,000 extra police officers would join 6,000 officers already deployed.

London has been the scene of three nights of fire and looting, as gangs of youths have been broken into shops, setting businesses ablaze and clashing with police in neighborhoods across the country.

The first riot happened in Tottenham on Saturday, where protesters clashed with police outside a station, as they were demanding justice for the Thursday shooting of 29-year-old Mark Duggan after police stopped a minicab he was driving.

Reuters has reported that politicians and police blamed the London riots, which is the worst in decades, on criminals and opportunistic hooligans. However, residents in the affected areas and some commentators paint a different picture and have attributed the unrest to local tensions and anger over economic hardship in a city where there is a growing gap between the haves and have-nots.

More than 450 arrests have been made since the start of the riots on Saturday and authorities have said the prisons in London were already reaching capacity. The newly detained are being shuttled to jails outside the capital, according to the Washington Post.

British leaders will be back in parliament on Thursday for more riot discussions.
