LAUNCESTON police have appealed for more information after receiving a new tip-off about deliberately-lit fires at Housing Tasmania properties.
There have been eight deliberately-lit house fires in the units at Pioneer Parade, Ravenswood, since May 2012.
The replacement cost for each is about $190,000.
Detective Sergeant Peter Roberts, of Northern Criminal Investigation Branch, said the fresh lead had given police a new line of inquiry.
"We are again asking any person who might have information regarding the people responsible for these fires, to contact us," he said.
"While these fires have a significant monetary value, they also have a significant impact on the community at large, in particular residents living within the Ravenswood area."
Earlier this month, a Ravenswood man pleaded guilty in the Launceston Magistrates Court to having lit two fires in his suburb, including the arson of a Rosetta Place house in December.
The man will face sentencing in the Launceston Supreme Court on April 28.
Police urge anyone with information about the Ravenswood fires to call Crime Stoppers on 1800 333 000 or Launceston detectives on 6336 3701.
