Police on Newfoundland's northeast coast believe someone in Bonavista knows who was behind a couple of suspicious fires last week, one of which destroyed a vacant house.

RCMP are asking residents to come forward with what they know about a fire that destroyed a home on April 19. A nearby shed was heavily damaged.

"Police believe that there are residents in the area that have information that could assist police in their effort to bring those responsible to justice," Sgt. Boyd Merrill said in a statement.

No one had lived in the house for several years, police said.
