Nicholas Tetro of 12 Edward Ave. was arrested outside his home at 2:40 a.m., police said. He was charged with third-degree robbery.
Tetro was scheduled for arraignment Monday in First District Court, Hempstead.
Police said Tetro entered the TD Bank branch at 500 East Old Country Rd. in Plainview at 11:50 a.m. Sunday, Dec. 27, and passed a note demanding cash to the 21-year-old female teller.
She handed over cash and Tetro fled on foot and onto South Oyster Bay Road, police said. There were five employees and nine customers in the bank at the time of the robbery, police said. No one was injured.
In a Monday news release, police did not say what led them to Tetro.
