Peel police have made an arrest in connection to the 2011 murder of an up-and-coming MMA fighter who was killed trying to stop an armed robbery.

Kearn Nedd, 28, died in hospital after he was shot at a charity poker tournament at the Rozz Banquet Hall in Brampton on April 16, 2011.

Police said that two masked men carrying firearms burst into the hall and fired several shots in a botched robbery attempt.

Nedd was shot after a scuffle with one of the gunmen. Police said he was acting as a Good Samaritan, as he ran to assist the organizer who was being attacked by the gunman.

The suspects escaped from the hall and fled to a waiting vehicle.

Nedd, who was a rising star in mixed-martial arts, was transported to Brampton Civic Hospital where he died of his injuries.

Investigators said on Wednesday that they found the pistol used to shoot Nedd in raid on June 9, 2011 in Mississauga.

Samir Abdelgadir, 30, has been charged with accessory after the fact to murder. Abdelgadir is in custody awaiting trial. He made a first court appearance on Wednesday.

Police are asking for assistance in identifying and locating two male suspects. They are described as black, with medium-dark complexion, about 6 feet tall, and with medium builds. Both appear to be in their early 20s.

Anyone with information is asked to contact officers at 905-453-2121 ext. 3205 or Crime Stoppers at 1-800-22-TIPS (8477).
