Police were called to a science fiction convention after an argument between two rival groups of fans.
Trouble flared at the fourth Norwich Sci-Fi and Film Convention at the University of East Anglia, organised by Norwich Star Wars Club.
Police were called after members of the rival Norwich Sci-Fi club arrived to get autographs from two Doctor Who actors at the event on Sunday.
Norfolk Police confirmed officers attended and spoke to both parties.
A spokesman said they had been called to reports of a man being assaulted at the convention.
Mr Poole said two other members of his club, one dressed as the 10th Doctor and the other as Judge Dredd, had waited outside the venue.
"This wasn't a fight between Star Wars fans and Doctor Who fans with lightsabers and sonic screwdrivers drawn," he said.
