Armed Irish police have seized a lorry cab that is believed to have taken to Belgium the refrigerated container in which 39 migrants died.
The blue Scania cab belongs to Ronan Hughes, a convicted cigarette smuggler, and was seized at Dublin port on Saturday. Mr Hughes is also understood to have leased the container in which the bodies were found.
The cab is believed to have delivered the container to Zeebrugge last week. Mr Hughes is a haulier from Co Monaghan on the border with Northern Ireland who was jailed in 2009 for smuggling six million cigarettes into the UK.
The operation to identify the dead and carry out post-mortem examinations continued over the weekend as blood and hair samples were shared with Vietnamese officials.
It is now believed that as many as 25 of the victims were from Vietnam. Accounts from families searching for missing relatives suggest the victims were among as many as 100 migrants who had paid to be slipped into the UK using the high-risk approach.
The cab seized in Dublin was taken to Santry police station in the north of the city. Like the cab that picked up the container in which the victims died, it has Bulgarian number plates.
The driver, Eamon Harrison, 23, was arrested on an unrelated warrant for assault and criminal damage dating back to September last year as he arrived at Dublin port from France on Saturday and appeared at Dublin district court the same day. He was remanded in custody to appear at Cloverhill district court on October 30.
His was the fifth arrest with links to the investigation into the deaths of eight women and 31 men were found in the back of a lorry on an industrial estate in Essex in the early hours of Wednesday morning.
Mr Hughes was jailed for two and a half years in 2009 after he was stopped going to Dover from France with 1,180 boxes of cigarettes hidden inside pallets of fruit. There is no suggestion that he was aware of the plot to smuggle migrants using the cab or the container.
The Times revealed last week that GPS data showed the container in which the 39 migrants died had made a previous trip to Belgium that week and on both journeys it stopped in Dunkirk and Calais.
