The black and white footage doesn’t look too sinister, but police say it shows bikies planning an attack on senior Comanchero Leslie “Lethal Les” Grantham last month.

The 51-year-old had been trying to leave the gang when police said members turned on him, burning off his tattoos, shooting him repeatedly in the upper body and thigh, and finally setting him alight.

Police say they are still trying to figure out where the incident took place as well as who took part in the attack.

The released footage shows groups of men meeting at Auburn Grove Train Station before the attack on May 15.

The trio swapped cars: a white and grey Holden ute, a black Nissan Navara, and a white Hyundai Tucson.

The Holden ute, with number plates 1BFC417, had Grantham inside and was later captured pulling into Rockingham Hospital where the victim was dumped.

The car has not been seen since.

Grantham is out of hospital but police say he is refusing to cooperate with detectives, instead staying silent on what happened to him and who did it.

Anyone with further information has been urged to contact police or Crime Stoppers on 1800 333 000.
