Thirteen men have been arrested in a series of early morning raids which aim to clampdown on crime within London's Tamil community.
Police say a minority are intimidating the community
The Sri Lankan men, all aged 18 to 25, were arrested on suspicion of crimes including theft, fraud and money laundering, as part of Operation Enver.
Around 250 police raided 22 address and seized items including swords, axes, credit cards and a credit card reader.
The raids took place in Brent, Harrow, Redbridge, Croydon and Newham.
Commander Alfred Hitchcock blamed a minority of people within the 110,000-strong community for violence and intimidation.
Profits from crime
He said: "The majority of the Sri Lankan community are very law abiding, but there are small groups of
people taking advantage, intimidating them and committing these offences.
"We have been looking at the criminality and violence within the Tamil community, we have made inroads with these arrests, but it is not the end of the process."
Five of the men were arrested at one address on suspicion of theft.
At a second address five more were arrested - two on suspicion of money laundering and three on suspected theft and fraud charges.
Two more men were being held over a suspected drug deal and another man was arrested on a warrant from Northampton.
Commander Hitchcock would not rule out the use of profits from crimes being used to fund the rebel Tamil Tigers in Sri Lanka, as well as for personal gain.
