Officers had aborted the pursuit of a car believed to be using cloned plates seconds before it crashed into a different police vehicle on the A66 near Middlesbrough, killing seven people, the police watchdog said.
Five males aged between 17 and 23 years old were killed when a Volkswagen Passat, which was being driven on the wrong side of the dual carriageway at South Bank, collided with a marked armed response vehicle on the A66 in Teesside early on Saturday.
