Five men have been arrested in the Lewisham area on suspicion of involvement in immigration offences and drug dealing.
Police executed two warrents on Tuesday that were aimed to disrupt an organised crime network that was operating within the borough after intelligence was received that illegal gambling and drugs supply were taking place at the addresses.
All five men were arrested at the same property. Two of the men were arrested for suspected illegal entry to the UK and one for suspected illegal entry into the UK and possession of a class A drug.
There was also one arrest for possession of a class A drug with intent to supply and one arrest for possession of what were believed to be counterfeit identification documents.
A large amount of cash was seized, along with the counterfeit documents and class A and B drugs.
No details were given about the second warrant.
Lewisham Police said they had been working alongside several other organisations when executing the warrants, including The Gambling Commission and the United Kingdom Border Agency.
