Detectives investigating the death of a police officer have said he died of “multiple injuries”, as they were given more time to question 10 suspects.
PC Andrew Harper, 28, was responding to a burglary report on Thursday in Berkshire when he was dragged along a road by a vehicle.
Ten males aged between 13 and 30 have been arrested on suspicion of murder.
Thames Valley Police said on Saturday it had been granted an extra 36 hours to question the suspects.
PC Harper, who got married four weeks ago, was killed on the A4 Bath Road in the village of Sulhamstead.
Det Supt Ailsa Kent told a press conference: “A post-mortem was carried out on Andrew’s body and the cause of death has been recorded as multiple injuries.
“The cause of death is consistent with our current belief that Andrew was caught between a vehicle and the road and then dragged for a distance.”
She said the 10 boys and men had been arrested at council-run caravan and mobile home site Four Houses Corner, about three miles from where PC Harper died, and remain in custody.
Officers are carrying out house to house inquiries, reviewing CCTV footage, interviewing witnesses and conducting forensic examinations, Det Supt Kent added.
