Police are warning residents just across the border of home invaders dressed in disguise.

Last Friday, a home in Peace River, Alberta was invaded by three men posing as repairmen.

They claimed to be investigating a gas-leak in the home. The RCMP say the men had a long-barreled weapon and a handgun.

In another incident last month, three men dressed as police officers went to a home in Grimshaw, Alberta.

Police say no one was hurt in either incident. One intruder is described as six foot eight, Caucasian and 30 to 45 years old.

Police are asking residents to check for identification and use caution when allowing people in their home.
