Scott Thomas Riley, 36, pleaded guilty in the Launceston Magistrates Court to evading police and a series of firearm charges.

Police prosecutor Katrina Woodgate told Magistrate Simon Brown that Riley was issued a family violence order in November 2019 which prohibited him from possessing a firearm or ammunition.

Riley, who had previously evaded police under aggravated circumstances, also pleaded guilty to driving while disqualified.

On March 28, police sought to intercept Riley's car for a random breath test when he accelerated away and dodged through the streets of Ravenswood.

"He pulled up near units in Faraday Street and when police pulled up he decamped on foot where he was also seen by a witness," Senior Constable Woodgate said.

"He scaled a fence and was located in a garden shed in Lambert Street."
