The Rebels, the country's biggest bikie gang, were involved in a series of tit-for-tat shootings with the Bandidos in Sydney's west in December .

The Canberra killings came only hours after NSW detectives arrested a senior Bandido Motorcycle Club member at his home in Sydney's south-west.

Dozens of detectives and tactical operations officers carried out a dawn raid on the home of Mahmoud Dib, the serjeant-at-arms of the Bandidos' Parramatta chapter.

Dib was taken to Auburn police station, where he was charged with six firearms offences.
A loaded, unregistered .45 calibre semi-automatic pistol was allegedly found in Dib's car, hours after it was raked with gunfire in a drive-by shooting on March 16.
He was refused bail at Burwood Local Court.

An associate of Dib who was at the court wearing a white singlet with the "Bandit" - a nickname of the Bandidos - tattooed on his throat, caused a commotion when he appeared to make a slashing movement near his throat to a news photographer.

He then spat on the photographer and was tackled to the ground by four police officers.
Dib was arrested in the early morning, hours after yet another Sydney drive-by shooting, although police have yet to link that to the latest gang violence.

A black BMW four-wheel-drive parked in the driveway of a house in Frances Street, Merrylands, was hit with several bullets about 8.45pm on Monday.

Five people, including three children aged 12, 11 and seven, were inside the house.
