MINNEAPOLIS (WCCO) -- Police are hoping surveillance image will help them identify the person who robbed a Coon Rapids bank last week.

The incident occurred at the Associated Healthcare Credit Union on Coon Rapids Boulevard NW Friday morning.

Police say the suspect entered the credit union, placed a bag on the counter and demanded money. The suspect, described as 5'6" tall and 160 lbs wearing "construction-worker-type clothing," made off with an undetermined amount of money.

Investigators are asking anyone with information to contact Detective Mike Plankers at 763-767-6481, or Anoka County Central Communications at 763-427-1212.

A reward is being offered for the arrest and conviction of the person responsible, but police wouldn't say how much.
