STAMFORD - Stamford police say a case that was originally called in as an armed robbery is now being treated as an inside job.

Police say the store clerk at Checks Cashed on West Main Street called 911 and reported the store had been robbed by a masked gunman at around 8:30 a.m.

Authorities say the 25-year-old clerk has been manipulating the store’s records for months and made up the robbery to cover his tracks. They say that more than $70,000 is missing from the store.

Police say the Checks Cashed location will have to be audited. They are waiting on an arrest warrant for the clerk.
