Canada police probe possible gas pipeline sabotage

* Sabotage incidents in same area last year

* Anti-terror police part of investigation

* Leak was discovered Wednesday, no injuries

VANCOUVER, British Columbia, July 2 (Reuters) - Canadian police investigated on Thursday if a leak at a natural gas pipeline in northeast British Columbia was linked to incidents of sabotage on energy facilities in the area last year.

The leak at a wellhead near Dawson Creek, British Columbia, was discovered early on Wednesday when EnCana Corp (ECA.TO: Quote, Profile, Research) workers noticed a drop in pipeline pressure, according to the Royal Canadian Mounted Police.

Local media reported the leak was caused by an explosion. There were no reports of injuries.

A police spokesman could not say if the incident was an explosion or linked to last year's bombings at EnCana facilities in the area, but said more information was expected to be released on Thursday.

Investigators from the RCMP's anti-terrorism unit were part of the investigation.

Four explosions damaged EnCana-owned pipeline facilities near the communities of Dawson Creek and Tomslake last year, and investigators believe they were linked to a letter warning EnCana to leave the area.
