A WOMAN was hit by a brick at the final match at Farrar Road.
The brick was hurled over the wall from St Paul's field during match against Prestatyn Town on Tuesday.
Fanswere separated by stewards to avoid further trouble as they exchanged heated chants.
A Bangor City chairman Dilwyn Jones said that the club was awaiting a security report on the match.
He added that two people were ejected from the stadium during the game.
"We'll do our own internal investigation and pin down individuals, and we'll take it from there.
"The club has a policy of reviewing every incident and taking the appropriate action thereafter," he said.
A North Wales Police spokesman said that no arrests had been made, but that investigations were ongoing.
Mr Jones praised the stewards' handling of the crowd on the day.
Vandals daubed the letters "CTFC" , the initials of rivals Caernarfon Town, on a Bangor City logo painted on the stadium wall the night before the match.
There is no evidence to suggest that anyone connected to Caernarfon Town was involved.
However, Mr Jones said that the graffiti was painted over before the game.
The club will not seek a prosecution over the vandalism.
Mr Jones added that the incidents did not affect the occasion, and that the club had not received formal complaints from Prestatyn Town or individuals.
North Wales Police will provide police cover for the return fixture on January 2.
