The former Nomads bikie gang boss Hassan "Sam" Ibrahim was targeted in a drive-by shooting when he was standing in the front yard of his parents' home in the western Sydney suburb of Merrylands just before 7pm (AEDT) on Thursday.

A light-coloured car drove past the house on Price Street, with Sam Ibrahim shot twice, once in each thigh.


Police believe the attack on the older brother of nightclub supremo John Ibrahim wasn't a random shooting.

Acting Gang Squad Commander Superintendent Wayne Hayes said the shooting was attempted murder, and he expected Mr Ibrahim knew who was after him.

"I do have concerns there may be revenge attacks," Supt Hayes told reporters on Friday. "I expect his co-operation."

Supt Hayes, who is yet to interview Mr Ibrahim, said it was too early to say whether a string of recent shootings and attacks on tattoo parlours in Sydney are linked to the incident.

The former bikie boss had two bullets removed from his legs at Westmead Hospital, where he was in a stable condition on Friday.

Neighbours told AAP they heard "at least" two blasts.

"I heard something but had no idea it was gunshots," said one woman, who asked not to be named. "There were at least two bangs. Maybe three."

It's believed Mr Ibrahim was outside the house with his mother, bodyguard and a family friend at the time of the shooting.

"It happened all in front of her eyes, she saw everything, she is in deep shock," Ray, a family friend, told the Seven Network.

The attack came less than two months after a drive-by shooting at the home of Mr Ibrahim's sister, Armani Stelio, in the northern suburb of Ryde.

About 20 bullets were fired into the house, but no one was hurt.

Following the attack on his sister's home, Mr Ibrahim was shown in television footage speaking to police at her property.

In June 2009, Mr Ibrahim's brother Fadi Ibrahim was shot five times as he sat with his girlfriend in his car outside his home in the lower north shore suburb of Castle Cove.DISCLAIMER:Text may be subject to copyright.This blog does not claim copyright to any such text.
