Veteran Fremantle defender Michael Johnson is reportedly under investigation by West Australian police after a Leederville kebab shop patron was allegedly assaulted in the early hours of Sunday.

The alleged victim, a Bunbury teacher, reported the matter at his local police station on Monday and also handed over a video of a man, he believes to be the Fremantle star in the shop with his pants down.

The teacher then claimed he was caught filming and struck by the man he believes to be Johnson.

The footage was shown on the Seven Network in Perth.

Fremantle released a statement on Monday and will refrain from further comments until further information was available.

“We have been made aware that Fremantle player Michael Johnson, who is on leave, was allegedly involved in an incident in Leederville at the weekend,” the club said.

“We are in the process of gathering all relevant information.

“We are not in a position to comment further until that process has been completed.”

Johnson played only four games for the Dockers last year because of a hamstring injury.
