THREE teenagers and a man accused of murdering PC Andrew Harper while he was investigating a reported burglary will appear at the Old Bailey later today.

Henry Long, 18, of College Piece, Mortimer near Reading, appeared at Reading Magistrates Court this morning, charged with the murder of PC Andrew Harper and theft of a quad bike.

In front of a packed public gallery, he crossed his arms as he confirmed his name, date of birth and address to District Judge Davinder Lachher.

The hearing lasted about 5 minutes.

Two 17-year-old boys, who spoke only to confirm their names and address, were also charged with the murder and theft of a quad bike. They cannot be named because of their age,

Thomas King, 21 from Basingstoke has also been charged with conspiracy to steal a quad bike and is released on bail. 

There was a heavy police presence at court and the public gallery was full.

The defendants' family and friends shouted "love you" as the three in custody were led away.

It comes after Abingdon-based officer PC Andrew Harper died while on duty in Reading. 

The 28-year-old police officer was responding to reports of a burglary when it happened on the A4 Bath Road in Berkshire on Thursday, August 15.

The three teenagers have been remanded in custody.

They are also due to appear at the central criminal court this afternoon.

Another man, 20-year-old Jed Foster, has already appeared in court charged with PC Harper's murder.

He is next due to appear at Reading Crown Court on November 20.
