Police in Launceston are investigating whether there are any links between three separate gun incidents in as many days.
In the latest attack, two unoccupied vehicles were shot at on Poplar Parade in Youngtown.
The first incident was reported at 8.50pm on Saturday, where the rear window of a Subaru was destroyed.
The following morning, a rear window of a bus was found to have been damaged.
“Police take all reports of alleged firearms discharge seriously and assure the community that all incidents will be investigated thoroughly,” said Inspector Michael Johnston.
Prior to the vehicle attacks, shots were fired into a home on Balfour Street, Launceston in the early hours of Saturday morning.
A man and woman were at home at the time, but no one was injured.
On Thursday night, a woman was shot in the back while sitting in a car in St Leonards, and had to have surgery for her injuries.
"This is the third firearms incident in Northern Tasmania is as many days, which is understandably concerning to police and the community," Inspector Johnston said.
But he denies it's evidence of a surge in gun crime.
"It's unfortunate and in fact quite concerning that we have three over three days, but I wouldn't say that it's an indication of a rise in the level of gun crime".
Police are urging anyone with information in relation to any of the firearm incidents to come forward.
