Ex-Bikie Boss Shot Dead in Sydney
Police fear there could be acts of revenge after former bikie boss Mahmoud "Mick" Hawi was gunned down and killed in a "planned and targeted" daylight attack outside a Sydney gym.
The ex-leader of the Comancheros was shot while in his car outside a Fitness First gym in Rockdale about midday on Thursday.
The 37-year-old went into cardiac arrest before being transferred to St George Hospital where he later died.
Hawi served time in jail over his role in the killing of Hells Angels associate Anthony Zervas who was bashed with a bollard during a brawl between the rival clubs at Sydney Airport in 2009.
Hawi's luxury black 4WD, parked in front of the gym's entrance on West Botany Street, was peppered with at least half a dozen bullets.
"This was a planned and targeted attack," Assistant Commissioner Mal Lanyon told reporters.
"This is something that we will not tolerate because of the potential for an innocent member of the public to be harmed."
The assistant commissioner said a man wearing dark clothing and a balaclava was reportedly seen by witnesses at the scene.
Police were "100 per cent committed" to finding out who was responsible, Mr Lanyon said.
"One of the things we will focus on - aside from the investigation - is ensuring that we put sufficient resources out there to prevent any retribution that may be considered as a result of this shooting.
"It's essential when we believe there could be links to organised crime that we take action to prevent that."
Detectives believe the shooter fled in a vehicle. A grey Mercedes was set alight in a nearby street shortly after the attack and police are investigating if it's linked.
Fitness First said it had closed the Rockdale gym until further notice.
