Alexander Victor Miller, 28, entered not guilty pleas in the ACT Magistrates Court on Monday to charges of possessing a prohibited firearm, possessing ammunition, and possessing a drug of dependence.

Miller – who is in the Alexander Maconochie Centre and did not appear in court – was represented by defence lawyer Peter Woodhouse.

Mr Woodhouse also entered guilty pleas on behalf of his client to unrelated charges of speeding, drug driving, and failing to appear.

Miller has been behind bars since his arrest earlier this month during a police operation targeting the Comanchero outlaw motorcycle gang.

A failed bail hearing heard the ACT chapter of the gang had recently split into two factions, sparking tit-for-tat violence, including a drive-by shooting and arson in Page and the shooting of a gang associate in Chifley, both in March.

Police allegedly found a sawn-off .38 rifle, ammunition, drugs, gloves, a black balaclava, cash, and other items in Miller’s car about 11.30pm on June 5.

The court heard police had seen Miller drive past the home of the rival member.

Miller applied for bail when he appeared in court on June 6, but it was refused.

On Monday, Magistrate Beth Campbell accepted the pleas and scheduled the matters to return to court in the coming months.

The traffic charges will come before the court in July, while the weapon and drugs counts will return to court in September.
