Dozens of bikie gang members and associates are in police sights as the hunt continues for those involved in a brazen daylight shooting incident in the Sydney suburb of Marrickville.

A 20-year-old man was shot in the chest and a 33-year-old man was hit in the buttocks inside a hairdresser on Marrickville Rd on Friday afternoon.

Two cars were set alight in neighbouring suburbs shortly after the shootings, with police treating the incidents as linked.

Detectives believe the shootings were targeted.

Police are also investigating possible links to the fatal shooting of cocaine kingpin and underworld figure Alen Moradian in Bondi Junction last month.

Criminal Groups Squad detectives have since taken over the investigation under Strike Force Orsino.

Detectives spoke with more than 25 alleged outlaw motorcycle gang (OMCG) associates over the weekend.

Associates were targeted in suburbs across Sydney, including the CBD, Wollongong and Katoomba.

Criminal Groups Squad commander, Detective Acting Superintendent Glyn Baker, said officers would continue to focus on gang associates.

“Whether through vehicle stops, doorknocks or compliance checks, our best detectives are on this case, relentlessly pursuing leads to find those responsible,” Det Supt Baker said.

“We are working closely with Raptor Squad to ensure that while inquiries are being made, OMCG associates continue to feel the insistent pressure from police.”
