A man who barricaded himself in a toilet told staff to 'f*** off' and said he was 'having a s***' when they asked him to leave.
The offender allegedly walked into the city centre premises around an hour beforehand and didn't buy anything, police said.
Concerned by his lengthy stay in the facilities, those working in the venue knocked on the door and asked him to vacate the premises.
When the man became verbally aggressive, staff called police, who moved him on, GMP City Centre tweeted.
No criminal offence was committed, Inspector Jon Middleton said.
