THE owner of an Osborne Park gym was the victim of blackmail on March 21.
About 10am on March 21, a man attended the gym and asked to speak with the owner.
The owner of the gym was ushered out the back door into the carpark and towards the rear of a vehicle where he was surrounded by three other men.
He was handed a document detailing he allegedly owed them a large sum of money and was threatened to sign it.
Police have released a CCTV image of a man who they believe can assist with their inquiries.
The man is described as having light skin, 40-45 years old, of a solid build, about 180 cm tall and a dark-coloured beard.
At the time of the incident, he was wearing a dark coloured short-sleeved shirt, long pants and black runners with a white sole.
