IT'S the birthday he'll never forget.
A Gladstone man was banned from a city pub after he headbutted a police car and copped a face full of capsicum spray at his 21st bash.
Jack David Salter was told not to enter Gladstone's Reef Hotel for 12 months, and scored a $750 fine and conviction after his party went awry.
The court heard the birthday boy had been celebrating with mates at a private function about 9.50pm on July 5 at The Reef Hotel, when things took a turn for the worse.
Police were called to a scene where security staff were trying to remove a group from the hotel.
As officers were arresting another person, Salter and a group charged the officers.
Police prosecutor Sergeant Sean Franklin said capsicum spray was used on Salter after he ran at police.
The agitated man then headbutted a police car.
Salter, who pleaded guilty to one count of public nuisance, told Magistrate Ron Muirhead on Tuesday a prior arrangement in regard to smoking had been made with the hotel.
A misunderstanding with security staff as to those arrangements, he said, was the cause of the incident.
Mr Muirhead said the defendant's behaviour was uncalled for.
"The bottom line is your behaviour was well out of line," Mr Muirhead said.
