Troubled Docker Harley Bennell is under the Western Australia police's investigation after being involved in a physical altercation with a bikie, according to a report by SEN's Sam McClure.

“It was in JLT2 in Mandurah when West Coast were playing Fremantle," McClure told SEN's Time On.

"Harley Bennell was watching on in the crowd, a discussion took place with a few men, one of whom was known to Bennell, but also known to Western Australian police and the organised crime squad.

“He is a bikie with the Coffin Cheaters motorcycle gang. This discussion, for whatever reason, has then turned physical and security intervened and offered to walk and escort Harley Bennell back to his car.

“This man at the centre of it is part of a broader investigation by the Western Australian organised crime squad. There’s no suggestion that Harley, in this particular incident, has done anything wrong. The AFL and Fremantle are both aware of the situation.

“The investigation is not into Harley, but he has now been embroiled and is at the centre of a broader investigation into the man he was having a conversation with and had a physical altercation with.

“What this altercation was about remains unknown, but the man is both known to police and to Harley himself.”

The incident comes after Bennell was kicked out of a Perth pub earlier in the off-season before suffering another injury setback to his calf.

The 26-year old was handed a one-year extension by Fremantle last August despite only playing two senior games for the club after crossing over from Gold Coast at the end of 2015.
