Jurors in the trial of three teenagers accused of the murder of PC Andrew Harper in Berkshire have been shown images of the car involved in his death, along with items strewn over the road where he died.

PC Andrew Harper died from catastrophic injuries while responding to reports of a burglary near Sulhamstead in August last year.

Photos of the 28-year-old's police badge, ID card, driving licence and roads policing card, which were all found on the roadside, were shown to the jury.

Jurors were told it was probable that PC Harper was unconscious from the start of his ordeal.

They were also shown dash-cam footage of fellow officers rushing to his aid.

The court heard how police responded very quickly to what was going on. Within moments of discovering PC Harper, they were chasing the defendants from the A4 Bath Road junction, to a caravan site four miles away.

They were shown CCTV of the two cars rushing down country roads at speeds of more than 50mph.

The prosecution argue the teenagers were trying to escape 'at all costs' and were 'prepared to inflict serious harm to get away'.
