NASHVILLE, Tenn. (WKRN) – A man who entered a Bellevue bank’s drive-thru line and allegedly passed a note to a bank teller threatening to detonate a bomb has been arrested.

According to the Metro Nashville Police Department, surveillance footage showed 37-year-old Mario Armstrong walking up to the drive-thru of Pinnacle Bank on Highway 70 South at approximately 4:55 p.m. on Tuesday, Aug. 8, and putting a demand note through the bank’s vacuum tube system.

The handwritten note reportedly said there was a bomb in the building and ordered the teller to send back $20,000 in big bills or the bomb would be detonated, which led the bank manager to call 911.

After passing the note, Armstrong fled the scene on foot, went behind a business, and was seen changing his clothes on surveillance footage, according to officials.

Authorities later found a man matching the suspect’s description walking along Highway 70 South near Hicks Road, less than two miles from the bank. Police said they stopped Armstrong, adding that he was compliant until officers asked to search his backpack.
