FOUR people have been arrested on suspicion or murdering PC Andrew Harper, who was allegedly dragged to his death by a vehicle while responding to a burglary.
The four are being questioned over PC Harper’s death in Sulhamstead, Berkshire on August 15.
They have been arrested on suspicion of murder and theft and are in custody.
Three of those arrested were originally detained August 16, but were released on bail until September, 12.
They were then re-bailed until 16 November, with a fourth suspect, a 21-year-old male, also arrested.
Around 100 cops carried out a series of warrants to arrest the four males.
Detective Superintendent Ailsa Kent, of the Thames Valley Police Major Crime Unit, said: “We are continuing to investigate the death of our colleague PC Andrew Harper, and today we have re-arrested three people in connection with this.
“In addition to these re-arrests, we have also arrested a further suspect, a 21-year-old man from Basingstoke.
“All four have been arrested on suspicion of murder and theft and are in our custody.
“This follows new evidence coming to light as the investigation has progressed in recent weeks.
“Members of the public might see an increased police presence at the locations of these warrants today. We appreciate the public’s patience and support while we progress these critical lines of enquiry.”
