Blinkhorn was being sought for attempted murder, aggravated assault, wearing a disguise while committing an offence and impersonating a police officer in the beating of Shawn Jack.

Police say Northside residents James Darren Clarke, 34, and Gordon William Bobbitt, 47, have been charged with obstruction of justice.

This follows the arrest of three people last week. Kyle William Nichol, 25, of North Sydney, Jennifer MacLeod, 22, of Boularderie and a 16-year-old girl all face charges of aggravated assault and wearing a disguise with intent to commit an offence.

Nichol, who is due to appear in court July 31, is also charged with attempted murder. MacLeod is due in court on Monday for a bail hearing.
