Today's action was the largest yet by the Metropolitan Police under the banner of Operation Maxim, an initiative to tackle organised immigration crime. The officers also targeted addresses in Upper Norwood, Anerley, Mitcham and Canning Town during the raids, which were supported by the Immigration Service and Passport Agency. The swoops were also timed to coincide with activity by the South African police service in Durban this morning. Among those arrested today was a Zimbabwean-born naturalised British citizen in his forties.
