The OPP's Organized Crime Enforcement Bureau is looking to the public for help in connection with two separate incidents that happened a week ago in Port Dover on Friday 13th.
In a release, police say the incidents involved threats of violence and intimidation between Hell's Angels and Outlaw members.
No other details are provided.
Last week, police issued another release warning attendees at the popular biker gathering, they may be unwittingly supporting known organized crime groups.
OPP advising "seemingly harmless activities like purchasing and wearing support gear or participating in charitable activities organized by these gangs directly fuel further illegal activities such as drug trafficking, violence and intimidation, and human trafficking."
The release goes on to say, "Friday the 13th is an opportunity for the criminal element to syphon huge profits from this large gathering."
The OPP warn the public "the open display or wearing of any recognized gang-related clothing or paraphernalia may put them at risk of being targeted by rival outlaw motorcycle gang members this weekend."
Anyone with information should immediately contact the Ontario Provincial Police at 1-888-310-1122. Should you wish to remain anonymous, you may call Crime Stoppers at 1-800-222-8477.
