STAMFORD - The man who allegedly robbed a Stamford bank and threatened to blow it up is in custody, officials say.

Police say 29-year-old Janseen Lewis walked into the TD Bank on Summer Street and threatened a teller, saying he had a bomb and would blow up the bank if anyone called the police. They say the teller gave Lewis $5,000 in cash and he calmly walked out of the door.

Investigators say that several hours later, Fairfield police saw the surveillance image of Lewis and tipped off Stamford police as to who he was. They say he had been in Fairfield acting suspiciously the night before.

Authorities say they went to Lewis's home in Stamford and located the money in his car, and he was arrested a short time later. Lewis said he never really had a bomb.
