RCMP and Wildland Fire Management officials suspect there's a firebug at work in the central Yukon community of Mayo.

They believe someone set fire to an abandoned building in the community Friday night.

By the time the fire was put out early Saturday morning it had burned to within 200 metres of the local church.

"This fire was inexcusable and had the potential to be very destructive." said Mayo Regional Duty Officer Dave Trudeau.

Wildland Fire Management communications officer George Maratos says they want to identify the culprit.

"Inexcusable really. Just very suspicious in nature and the community had been dealing with this the past two summers now and we're just asking anyone with information regarding suspicious burning or if you hear anything around town to either contact the local RCMP or the Mayo Fire district office." Maratos said.

Several suspicious fires started around the community of Mayo last summer.

"All human caused fires are preventable, but when you get continuous fires of this nature in the same community it is a concern and not something to play around with. That's why we are asking the community to really be aware of any situation and if you do have any information please share it with the right people."

The weekend fire was the 13th in the territory this season.

It burned .5 hectares, but took six firefighters and a handful of volunteers to put it out.
