Bangor manager Lee Feeney said he thought the result of his side's 2-2 draw against Crusaders "was influenced by the referee".
The Seasiders led 2-0 thanks to goals from Harry Lynch and Ben Cushnie, but two goals in the second half from Stewart Nixon and Fraser Bryden meant the points were shared at Seaview.
Feeney was left bemused following the game and believed that his side should have been awarded a penalty in the final minutes of the game.
"Purely frustrated," Feeney told BBC Sport NI.
"We are 2-0 up and I think we deserved it. Crusaders played some great football, but we have a game plan.
"Ben Arthurs is clean through on the 92nd minute and the man comes straight through from behind and the referee doesn't give a penalty to us. Extremely frustrated and I think the result was influenced by the referee."
The result means that Bangor are now without a win in their last five Premiership matches with the Crues without a victory in their last four games.
Crusaders manager Declan Caddell praised his players after the draw with his side remaining in 11th position on goal difference.
"We showed character today and that is the main thing for me," Caddell told BBC Sport NI.
"Too many times we have fallen behind and folded and the boys showed character, stood up and there was probably only one team pushing for the winner at the end.
"I am delighted for them. We had a tough few weeks there and this was a game we wanted to get as many points as we could from. We got one and we'll move on."
