A DRUG dealer who repeatedly smashed a cider bottle over the head of his ‘runner’ while on bail for punching a woman has been jailed.

Callum Johnson was also caught selling drugs to an undercover police officer who infiltrated town centre dealers last year.

Now the 26-year-old has been jailed for eight years and four months, and when he is released he will be on licence for an extra four years.

Johnson was wanted by police following Operation Harness when he attacked Brian Roberts over the quality of drugs he had collected for him.

Colin Meeke, prosecuting, told Swindon Crown Court the victim ran errands for the defendant and on March 19 had been to town to collect some cocaine.

Johnson then summoned him to the home of Roberts’ girlfriend Michaela Walker, telling him he was upset about the goods, and when he arrived he was clearly angry.

Mr Meeke said: “He came out of the bathroom and hit the complainant over the head with a bottle.

“He hit him several times with either the bottle or a fist. Mr Roberts lost track of how many times he was struck.

“The defendant appeared angry, accusing Mr Roberts of having stolen his cocaine. All this happened in Miss Walker’s property, she saw the brutality of the attack.

“The defendant also picked up a screwdriver and was jabbing the complainant with it, causing some scrapes to his leg.”

As a result of the assault Mr Roberts had a swollen bottom lip and loose tooth, and needed to have four sutures in his head.

The violence came three months after Johnson knocked a woman to the ground after he was thrown out of a town centre club.

Aimee Badham and a friend were walking past Revolution shortly after midnight on December 20 when they heard shouting from the door.

Johnson, who was a stranger to her, was squaring up to door staff and took his coat off as he appeared to want to fight with them.

The other girl picked up the coat as a joke and pretended to run off with it and the defendant turned on Miss Badham and punched her to the face.

Mr Meeke said that Johnson was caught supplying heroin and cocaine on five occasions in October and December in the police sting.

Johnson, of no fixed abode but previously living in Wroughton, admitted GBH with intent, ABH, five counts of supplying drugs and two of possession.

The court heard he had numerous previous convictions including wounding with intent and GBH as well as possessing a knife.

Rob Ross, defending, said the assault on the friend was down to his believing he had been given bicarbonate of soda to sell instead of cocaine and the woman was through drunkenness.

He got back involved in the drugs world after a violent dealer who said he owed him money got him to sell the drugs for him.

The assault on the friend was down to his believing he had been given bicarbonate of soda to sell instead of cocaine and the woman was through drunkenness.

Jailing him, Judge Douglas Field said: “You were selling drugs on a pretty regular basis. We can see the number of days you were selling to undercover police officers.”
