A thug who brutally stabbed a man after he went to police with information about his gangster father-in-law was today jailed for seven years.

Christopher Kavanagh pounced on Robert Forbes in Paisley, Renfrewshire in August 2017.

The 29-year-old is the son of law of jailed underworld figure Robert Pickett.

Pickett was one of six thugs locked up for a total of 104 years in May for his role in a savage gangland murder plot.

A judge heard earlier this month how Mr Forbes was targeted after alerting police he had “information” on the 54-year-old.

Kavanagh pled guilty to assaulting Mr Forbes to his severe injury, permanent disfigurement and danger of his life.

He had originally faced an attempted murder allegation.

Judge Lord Clark told Kavanagh: “This was a brutal and planned attack.

“You moved to intimidate Mr Forbes, he stumbled and fell and you stabbed him on the face, body and hand.”

Pickett – currently serving a 16-year sentence – was accused of trying to kill Mr Forbes, but had his not guilty plea accepted.

Kavanagh struck on August 17 2017 after the victim got out his van in Paisley's Causeyside Street.

Mr Kearney: “Around this time, the former co-accused (Pickett) arrived in his vehicle and was observed to cross the road.

“This was in the general direction of Mr Forbes, who appeared to take fright and ran.”

Mr Forbes ended up falling before Kavanagh stabbed him three times on the face, body and hand in a “swift attack” lasting only seconds.

Members of the public in the busy street raced to help the blood-drenched victim.

Mr Forbes was heard stating: “They have got me. They found me.”

He later needed 17 stitches for a facial wound, which left him scarred for life.
