A teenager smashed up his dad’s car with a hammer - then called the police on himself.

Lee Jack Johnson, 18, attacked his dad’s Vauxhall Vectra after a furious row turned violent.

He then called the police who tried to restrain him because of his ‘erratic behaviour’.

During the mele a growing crowd of onlookers became ‘hostile’ towards police.

At Stockport magistrates’ court, Johnson of Eaton Lane, Macclesfield, admitted criminal damage, resisting arrest, and using threatening, abusive words, behaviour likely to cause harassment, alarm or distress.

Kate Gaskell, prosecuting, told the court the police had been called out to the home several times before the incident on November 20.

She said: “Police were called to an address by the defendant who told them he had smashed up his dad’s car with a hammer after they had been arguing.

“When officers arrived Johnson was behaving very erratically and started shouting and swearing. Officers tried to calm him down.

“Police also became aware of a number of children starting to gather in the area to see what was going on.

“The crowd was increasing and becoming more hostile towards the police.

“Police then started to restrain Johnson but as Pc Dobson started to put the handcuffs on Johnson tensed his upper body and gritted his teeth aggressively.

“A female officer then drew her spray and warned him she would use it if he didn’t calm down.

“The crowd shouted their displeasure and began to act in a similar manner to the defendant.”

John Gallagher, defending Johnson, said: “Quite clearly if the defendant hadn’t called the police he wouldn’t be here in court.

“On the day in question he had been arguing with his mother when his father came in.

“Tensions were high following the death of his grandfather on his mother’s side.

“The father got involved in the row and it escalated to pushing and shoving.

“Johnson then threatened to damage the car and then followed through with the threat.”

Magistrates sentenced Johnson to a 12 month conditional discharge.

The court heard that Johnson’s father was not pursuing a claim for compensation.
