A violent thug attacked a new father with a bottle at a baby head wetting party, a court heard.
Jonathon Johnstone struck his victim, who was celebrating the birth of his child, on the head with a bottle before jabbing him in the leg.
Johnstone was handed 16 months youth custody at Preston Crown Court by Judge Beverley Lunt, who said he had a “worrying history of violence”.
The 20-year-old, of Bowland Crescent, Grange Park, had pleaded guilty to unlawful wounding and theft.
Emma Kehoe, prosecuting, said the victim and his friend were celebrating in a flat on Boothley Road, Layton, last October.
They became aware that two men – Johnstone and his friend – were outside the flat.
The victim’s friend knew the man Johnstone was with and so they were invited in.
Something triggered the defendant to lose his temper.
Miss Kehoe said: “The next thing the victim recalled was the defendant in front of him, with a broken bottle in his hand and jabbing it towards his body.”
The victim managed to flee his flat but when he returned, he noticed some cash, a bottle of vodka, trainers and some aftershave had been taken.
He went on to have his leg injury cleaned and dressed in hospital.
Johnstone had a previous offence for wounding on his record from when he was 16.
Chris Hudson, defending, said: “The defendant thought the other person wanted to go to the address to buy cocaine.
“An argument arose. It was the defendant’s understanding, perhaps affected by 10 pints he had consumed, that his friend wasn’t happy about cocaine he had allegedly been supplied with.”
Judge Lunt said Johnstone had sought to blacken the name of the victim by suggesting he was a drug dealer. She said she rejected that claim.
She added: “You were in no danger in this home.
“You turned this into a violent incident and used a bottle twice. This was an unprovoked attack”.
