British police on Sunday charged a third man over the deaths of 39 Vietnamese migrants found in the back of a refrigerated truck last month.

Christopher Kennedy, 23, was pulled over in the early hours Friday as he drove on a highway in Buckinghamshire, Essex Police said.

He was charged with conspiracy to arrange or facilitate the travel of people with a view to exploitation and conspiracy to facilitate the commission of a breach of UK immigration law, officials said.

Kennedy, of Darkley in Northern Ireland, is due in Chelmsford Magistrates’ Court on Monday.

Maurice Robinson, 25, who was driving the truck in Essex on Oct. 23 when it was found with the bodies, has been charged with 39 counts of manslaughter and conspiracy to traffic people.

Eamonn Harrison, 22, also faces the same charges and British authorities are trying to get him extradited from Ireland, according to police.

Numerous other arrests have been made in Vietnam, where all 39 immigrants were from originally.
