British police said on Wednesday they had charged another man as part of their investigation into the deaths of 39 Vietnamese migrants found dead in the back of a truck near London last year.
Alexandru-Ovidiu Hanga, 27, was charged with an immigration offense and was due to appear later at Basildon Magistrates' Court, east of London.
Detectives also said they wanted to speak to any other Vietnamese nationals who had entered Britain illegally via a similar route through the port of Purfleet.
