Owen Smith was handed a 14-year sentence at Hove Crown Court yesterday, following his horrific attack on PC Ellie Young.
Moments before the fight the unemployed 29-year-old and another armed accomplice were caught on CCTV ransacking the store at a garage in Horsham, West Sussex.
The pair, wearing balaclavas and armed with baseball bats, threatened two members of staff at 12.30am on July 6.
The robbers grabbed cash from tills and snatched cigarettes and alcohol from shelves.
During the raid a staff member managed to escape and alert the police, who arrived and were assessing the scene.
But by chance, a routine patrol car also drew up at the garage and discovered the crime in progress.
Smith saw PC Young arrive and footage shows him running toward the car. He is seen fighting with the officer before throwing her to the forecourt, and climbing into the driver’s seat.
She was left with arm, leg, shoulder and neck injuries but continued to try to tackle Smith with colleague Pc Vicky Canales.
Back-up police and bystanders came to the rescue seconds later as Smith attempted to escape. He was Tasered and arrested.
Smith, of no fixed address, previously admitted assault by beating a police constable, possession of a baseball bat as an offensive weapon, robbery and taking a police vehicle without consent.
Detective Chief Inspector Justina Beeken said: “Watching the CCTV of Owen Smith attacking our officers is absolutely harrowing, not least due to the ferocity of the attack, and I commend the officers’ bravery and commitment that evening in arresting him.
No officer should be attacked while doing their job and I am thankful that no officers were more seriously hurt
“No officer should be attacked while doing their job and I am thankful that no officers were more seriously hurt.”
She also commended the members of the public who tried to help “without a moment’s thought for their own safety” and Tesco staff members who were threatened at work.
However, police are still hunting for his accomplice, who escaped and remains on the run.
