Here is a timeline of events in the case of Pc Andrew Harper.

- August 15 2019, 4.50pm: Henry Long, Albert Bowers, Jessie Cole and Thomas King arrive at the home of Peter Wallis in Bradfield Southend, Berkshire, to steal his £10,000 quad bike.

They are confronted by Mr Wallis and leave empty handed.

- 11.10pm: Long, Bowers and Cole return to Mr Wallis's house and, over 15 minutes, steal his quad bike.

It is attached to a Seat Toledo by a strap and ridden by Cole.

- 11.17pm: Mr Wallis makes a 999 call to report a theft in progress. He says: "I've got four masked men outside my house and they've got weapons."

Pc Harper and his crew mate Pc Andrew Shaw are nearby in a BMW car, having already finished their shift.


- 11.28.17: The officers get a first glimpse of the Seat headlights approaching their car in Admoor Lane.

The vehicles stop, facing each other around 5m apart.

Eight seconds later, Long mounts the verge as he drives around the police car.

Cole is on foot behind the Seat. Having unhitched the quad bike, he tries to get back in the Seat.

Cole runs past the police car, pursued by Pc Harper, and dives through the Seat passenger window, the Old Bailey is told.

- 11.28.46: Pc Harper has almost reached the car and Cole but runs into the loop of the strapping trailing from the boot.

He is dragged away as Long accelerates off, jurors are told.

The whole incident takes around 30 seconds.
