A man with a gun is holding police at bay at a house in Launceston, with several shots fired since the stand-off began at 4:30pm today.
Police said no-one has been injured.
A number of homes in Reatta Road, Trevallyn, have been evacuated “as a precaution”, police said.
Police negotiators are on the scene and are attempting to convince the man to surrender.
More to come.
