Pc Andrew Harper's memorial service has honoured the brave hero on the year anniversary of death this morning.

Officers from Thames Valley Police have gathered at Newbury police station in Berkshire for one of several services being held on Friday.

Other memorials are being held in Sulhamstead, Berkshire, and Abingdon, Oxfordshire, to remember Pc Harper who was killed when trying to stop thieves fleeing after they stole a quad bike.

Henry Long, 19, and 18-year-olds Jessie Cole and Albert Bowers were jailed for the 28-year-old newlywed's manslaughter after they were cleared of murder.

Addressing the gathered officers at Newbury police station, Inspector Al Hawkett said: "We gather here today, as we did a year ago, to remember Pc Andrew Harper, who gave his life on behalf of others."

Mr Hawkett said Pc Harper's death had affected the whole force and the wider policing family over the past year.

He added: "Andrew was a brave young police officer, killed whilst doing the job that he loved.

"He was a good man who believed in policing.

"His dedication to protect the public from harm is testament to his courage and professionalism."

A wreath will also be laid and a minute's silence observed while the flag outside Newbury police station was at half mast for the memorial service.

Reverend Chris Maguire also gave a tribute to the officer.

He said: "Andrew, we remember you in the stories and laughter, the secrets of friendship that we treasure, in the risk of vulnerability, encouragement and the support you offered, we remember you.

"In the depths of our sharing, in our struggling, our caring, our living. We will always remember you.

"As we pause today to remember Andrew, we give thanks for his service and deeply saddened that he lost his life while protecting others."

Saturday, the actual anniversary date, has been left free of commemorations so that PC Harper's family and colleagues "can mark that date however they wish to", Thames Valley Police said in a statement.

PC Harper died after he was caught in a crane strap dangling from the back of a Seat Toledo and dragged to his death.

PC Harper's widow, Lissie Harper, and his mother Deborah Adlam, have launched a campaign backed by the Police Federation of England and Wales,  calling for full-life prison terms for those who kill emergency services workers.

Lissie said: "I pledge to my late husband to never stop until I have made the difference that this country clearly needs.

"I vow to stand strong and firm with so many other honourable people in our country to make the changes that we clearly know to be justified."

Speaking to media outside the Old Bailey after sentencing, she said: "The results from this trial I had hoped would bring justice but in reality make no difference to the heart-wrenching pain I will continue to feel for the rest of my life."

Heartbroken mum Debbie, 53, said: "We want to bring in something called Andrew's Law - we want to change this so that you are sentenced to a proper amount of time and that defines the crime that you've committed.

"We're hoping for a mandatory sentence with no early release, no reductions for being a certain age.

"You've killed somebody who is out there to do a good job, to protect the country, and you have taken their life. You need to pay for that."

Launching her campaign on Wednesday, Debbie said: "We've come to realise that, with the outcome of the trial as it stands, something needs to change.

"He is worth much more than this and we've been thinking for some time that something needs to be brought in to protect our police officers.

"They are going out day after day and they are putting themselves into terrible dangers - I think about the officers that were there that evening when Andrew lost his life and the things that they see and the things that they have to cope with.

"Then they just get their uniform on, and off they go again time and time again, and if somebody doesn't stand up and look after them when there's an injury or somebody's killed - we see from this experience that they are not being protected.

"There's nobody looking out for them and we aim to change that."
