A police car smashed into another car and a property in Hove in the early hours of this morning (Tuesday 17 December).
The woman driving the other car suffered minor injuries and was taken to hospital for medical checks.
The crash woke the two occupants of the flat worst affected by the crash, Nigel Merle and Franck Cleret.
Mr Merle said: “We felt the full impact of the car.
“My friend woke up screaming from his sleep and we felt the vibrations as the wall and the windows exploded on the first floor.
“We were very fortunate to survive it as the car could have exploded and worse.
“The ambulance and the firefighters arrived to clear the scene of the accident this morning.”
An investigation is under way and will look into whether the crash happened during a chase.
