MORE THAN 369,000 people have now signed a petition to overturn the verdict of PC Andrew Harper's killers' trial.

Last month, the three teenagers involved were convicted of manslaughter as opposed to murder, and have since been sentenced.

The sentencing is being looked into by the Attorney General following a public outcry that the prison time decided was too lenient.

Henry Long, 19, and 18-year-olds Jessie Cole and Albert Bowers were sentenced at the Old Bailey in July for PC Harper's manslaughter, and were handed a sentence of 16 years (Long) and 13 years (Cole and Bowers).

The 28-year-old newlywed, a traffic officer for Thames Valley Police, died in horrific circumstances on August 15 last year when he tried to stop the trio fleeing after they stole a quadbike in Stanford Dingley, West Berkshire.

He was caught in a crane strap dangling from the back of a Seat Toledo driven by Long, and dragged to his death.

Since the verdict, a petition to overturn the 'miscarriage of justice' has been launched and has been backed by PC Harper's family.

It reads: "Three men hug as they are CLEARED of murdering PC Andrew Harper, but convicted of manslaughter as his widow weeps in court. The three killers had laughed and joked with each other during the trial and when Long was charged he said he 'didn't give a ****.'

"The men who dragged officer for a mile behind getaway car as he tried to stop them stealing a quad bike are convicted of manslaughter - as it emerges police had to protect jury from intimidation."

A spokesman for the Attorney General's Office recently said: "The Attorney General's thoughts are with the family and friends of Pc Andrew Harper at this difficult time.

"I can confirm that we have received a request for the cases of Henry Long, Albert Bowers and Jessie Cole to be considered under the unduly lenient sentence scheme.

"The Law Officers have 28 days from sentencing to consider the case."

PC Harper's widow Lissie is also campaigning for a new law in her late husband's name.

'Andrew's Law' would see that anyone convicted of killing a police officer, firefighter, nurse, doctor or paramedic is jailed for life.

Lissie, who is working in conjunction with the Police Federation of England and Wales on the campaign - intends to call for the law change in high-profile meetings with Prime Minister Boris Johnson and Home Secretary Priti Patel in coming weeks.
