Fort Collins police are searching for an armed man who they say robbed the Public Service Credit Union branch in Old Town on Monday.

Fort Colllins police announced Thursday that the male suspect entered the credit union at 319 S. Meldrum St. around 5:45 p.m., displayed a gun and demanded money from an employee. The suspect left with an undisclosed amount of money, according to a Fort Collins police news release.

No one was injured during the incident.

Police have notified the FBI and are following potential leads. Officers are seeking the public's help in identifying the man, who police describe as "darker-skinned" and possibly Asian or Hispanic, standing between 5 feet, 5 inches and 5 feet, 8 inches tall.

It is standard procedure to notify the FBI of all bank robberies, according to Fort Collins police spokeswoman Kate Kimble.

According to the FBI's website, the agency provides assistance to state and local authorities in bank robbery investigations but focuses on suspects who pose the greatest threat to public safety, such as serial offenders who cross jurisdictions.

Anyone with information about the robbery is asked to contact Detective Adam Braun at 970-221-6580 or Crime Stoppers of Larimer County at 970-221-6868 or stopcriminals.org. People can remain anonymous and might be eligible for a cash reward.
