A convicted killer who tried to stab a mechanic after being unhappy with his car repairs was jailed for 14 months.

Fergus Barr, 47, wielded a six inch blade at Muhammad Usman at PAK Motors, Glasgow, in October 2019.

Barr, a former employee, sent his BMW to be repaired due to an oil leak.

Barr “wasn’t satisfied” with the work done by Mr Usman and threatened to burn down the garage.

Mr Usman was forced hide from Barr after he produced a knife from the boot of the car.

Barr pled guilty at Glasgow Sheriff Court to the assault on Mr Usman and acting in a threatening or abusive manner.

The court heard Barr put his car into the garage in Glasgow’s Ibrox area to sort an “oil leak.”

Prosecutor Derek Buchanan said: “He wasn’t satisfied with the work carried out and began to shout and swear.

“He stated he would burn the garage down and he would kick Mr Usman’s a**e.”

Mr Usman tried to calm down the enraged man, but failed to do so.

Mr Buchanan said: “Barr opened the boot and took out a yellow bladed item and approached Mr Usman, making motions with it.

“Mr Usman took refuge in the rear of the garage.”

Barr fled the scene in his car and was later arrested.

Lawyer, Roberto Marini, defending, told the court Barr had lost several family members, including his mother, and was having trouble dealing with his emotions.

He added: “He stupidly acted in this manner.”

Sheriff Martin Jones QC told Barr: “Due to the gravity of your record there is no other appropriate disposal other than jail."

Barr was convicted of culpable homicide in 2004 and received a four-year jail sentence.
