LONDON — British police have launched a murder investigation after the bodies of 39 people were found in a truck container outside of London.
The truck was discovered at an industrial park in the early hours of Wednesday morning local time, and all 39 people inside were found dead at the scene, police said.
The driver, a 25-year old-man from Northern Ireland, has been arrested on suspicion of murder.
Police believe the vehicle came from Bulgaria and entered the U.K. on Saturday. One of the victims was a teenager and all the rest were adults, they said.
The truck was found at Waterglade Industrial Park in the town of Grays in the county of Essex, around 15 miles east of central London.
At a news conference Wednesday, Deputy Chief Constable Pippa Mills of Essex police called it a “tragic discovery” and said “the identification of the victims remains our number-one priority.”
“This is an absolute tragedy and a very sad day for Essex Police in the local community,” the detective chief constable said. “We will continue to work alongside many other partner agencies to find out what led to these deaths. I’d like to appeal for anyone who has any information to contact my offices.”
Prime Minister Boris Johnson tweeted that he was “appalled by this tragic incident,” adding that the government would work with police to establish what happened. Priti Patel, the U.K.’s interior minister, tweeted that she was “shocked and saddened by this utterly tragic incident.”
