DEARBORN, Mich. -

Dearborn Police say the Bank of America on Michigan Avenue near Oakman was robbed Friday morning.

Authories say the bank was robbed by a lone suspect, who entered the bank, announced a hold-up and implied he was armed.

Police describe the robbery suspect as an African-American male in his twenties around 6' tall and with an average build.

The man was wearing a bright green safety vest with the word "visitor" printed on the back, a light-colored floppy hat, white T-shirt and green camouflage pants, according to police.

Police say the suspect escaped the bank with an undetermined amount of cash and likely fled in a vehicle northbound on Oakman from Michigan Ave.

The vehicle was described as a deep purple Chrysler.

"Our investigation is ongoing and we believe assistance from the community will be crucial in making a quick arrest," says Dearborn Chief of Police Ronald Haddad.

Also in Dearborn, police were called to a report of a bomb threat at a Walgreen's drug store on Michigan Avenue and Greenfield.

Investigators found no bomb and determined it was a false alarm.  It is not known if that report was connected to the bank robbery.

Anyone with any information related to the robbery is asked to please contact Dearborn Police at 313-943-2241.
