An agency worker has been sentenced to 20 months after he threatened an employee of his former recruitment agency with an imitation gun following his dismissal, reports the Grimsby Telegraph.

Jack Raithby, of Immingham near Grimsby, approached Carrie Jolly and her brother Craig in July last year after his contract was terminated; for which he blamed Ms Jolly, saying to Police after his arrest: “She got me the sack.”

He approached Mr Jolly, who it was alleged Mr Raithby used to bully at school, and said: “I have a gun and I am going to shoot you.”

He pulled out a BB gun, which fires pellets, from a carrier bag and hit Mr Jolly in the face with it. He then proceeded to follow the brother and sister to Mr Jolly’s girlfriend’s house where he shouted abuse at them through the letterbox.

Following his arrest, police searched his home and found amphetamines with a street value of over £1,200. He was also in possession of a BB gun and ammunition, which he was prohibited from owning, as a result of a previous offence.

He claimed that the drugs were not his and he was only looking after them for someone else.

Sentencing Mr Raithby to a total of 20 months, Judge David Tremberg said it was "a nasty revenge attack".
