More arrests over gang shootings in Sydney

Two more men have been arrested and charged over a series of shootings in Sydney linked to the notorious Brothers for Life gang.

Police say the latest arrests bring to 15 the number of people charged over last year's shootings, in which a 13-year-old girl and six men were shot and injured.

Shortly after 6.30am (AEDT) on Tuesday detectives attached to Strike Force Sitella arrested a 23-year-old man at a home in Miller, in Sydney's southwest.

It's alleged he was involved in the shooting of a property at Eagle Vale on August 2 last year.

The man appeared in Campbelltown Local Court on charges involving break and enter, and was denied bail to reappear on April 16.

On Monday a 65-year-old man was arrested at a Pendle Hill property where police executed a search warrant and seized a rifle cartridge and cannabis plants.

It's alleged the man sold a prohibited firearm to a senior member of the Brothers for Life Blacktown faction last year.

He appeared in Parramatta Local Court on Tuesday on firearms and drug charges, where he was granted conditional bail to reappear on March 20.

Strike Force Sitella was formed to investigate seven shootings carried out in Sydney between July and November last year.

In one incident at a home in Blacktown a 13-year-old girl was shot in the back.

Detectives have previously alleged a battle between the Brothers for Life gang's Blacktown chapter and its Bankstown sister chapter was behind the spate of shootings.
