A MAN who killed a policeman is guilty of wounding a prison officer using a “deadly” homemade weapon at a Worcestershire prison.

David Bieber used the pronged iron bar to repeatedly stab Alison Smith at the Long Lartin, near Evesham, in 2017.

Bieber is serving life for the murder of PC Ian Broadhurst and the attempted murder of two of his colleagues.

A week-long trial at Worcester Crown Court was told only good fortune had seen Ms Smith escape life-changing injury or even death, as she used an arm to protect her head.

Jurors cleared Bieber of attempted murder but convicted him of wounding with intent and possessing an unauthorised weapon.

Victim Ms Smith hit out at the killer for “stalling” justice by sacking lawyers to delay his trial.

The prison worker, who now has a different operational role, said the impact has been life-changing.

“I could have been killed on that day and genuinely believed I was going to be."

Jurors were shown CCTV of the attack but were not made aware of Bieber’s previous conviction for murder until after returning the verdicts.

The 56-year-old said, as a former US Marine, he could have killed Ms Smith with his bare hands and had put on a “show” in which he “pulled his punches”.

Although he conceded that the weapon obtained from another prisoner was “deadly”, he said it was necessary to make the incident serious enough to trigger a transfer.

But prosecutors said Bieber’s account to the court was an act designed to cover up his efforts to “get revenge on the prison service” after his medication for pain and anxiety was cut by prison doctors.

Prosecutor Simon Phillips described it as a "frenzied attack" and officers quickly came to Ms Smith’s aid after she screamed, restraining Bieber and disarming him.

She was later treated in hospital for cuts to her mouth and chin and four wounds to her right arm.

Bieber was told he will be sentenced on September 13, Judge Nicolas Cartwright warning he may see a period of years added to his current minimum term of 37 years.

PC Broadhurst was shot in Leeds at point blank range on Boxing Day 2003.

Bieber, a former kickboxer, was hunted by US police for eight years before he shot the officer.

The bodybuilding fanatic is also accused of paying a hitman to kill a love rival in Florida in 1995 and would face extradition if he is ever deemed safe to be granted parole in the UK.
