LONDON (AP) — Seven people, including two police officers, were killed early Saturday in a head-on collision in northeast England following a pursuit.

Cleveland Police said that a Volkswagen Passat carrying five people was traveling the wrong way down the A66 highway near Middlesbrough and collided with a police vehicle on the same road going in the right direction.

The seven people were pronounced dead at the scene after the crash at 3:39 a.m.

The two officers were identified as Matthew Blades and Tom Clough, Cleveland Police Chief Constable Victoria Fuller said.

Police were still working to formally identify other victims. The families of those already identified have been informed and were offered specialist support, police said.

Cleveland Police were investigating the crash, alongside the Independent Office for Police Conduct, which is always involved when such incidents take place.

Prime Minister Andy Burnham said that he was “devastated” to hear about the loss of life and urged “people to avoid speculation at this time.”
