High River RCMP have released a composite sketch of a suspect in an armed robbery at a home in Aldersyde Tuesday.

RCMP were called out Tuesday afternoon when a man returned home and found his front door open and a strange vehicle in the driveway.

When he entered the home and called out, a man came running out of one of the rooms.

The resident gave chase but the suspect turned, showed a gun and threatened him.

He fled in a mid 2000's black Honda Civic, two door hatchback with tinted windows and powder blue spiked rims.
