This is the moment a Bristol man was caught on camera overtaking an unmarked police car on the M4 at up to 150mph. An officer was on patrol on the westbound carriageway of the motorway between Junctions 15 and 16 in the early hours of November 14, when she became aware of a vehicle travelling behind her and approaching her rapidly.
As the silver Mercedes passed her unmarked police car, it was clear that it was being driven well over the speed limit so she radioed for support from colleagues. It was monitored by police to be travelling at speeds between 120mph and 150mph, staying in lanes two and three, despite lane one being clear, so was pulled over by police.
The driver Sajawal Khan, 23, of Stottbury Road, Bristol, had three passengers in the car and said he was travelling home from London back towards Bristol after celebrating his birthday.
