Portland police on Saturday arrested a 42-year-old man and charged him with the robbery Friday of the University Credit Union at 391 Forest Ave.

According to police, officers noticed Thomas Monat of Portland walking on Forest Avenue just a few blocks away from where he allegedly handed a credit union teller a threatening note and made off with an undisclosed amount of cash at 3:40 p.m. Friday. Monat, police said, rode off after the robbery on a bicycle.

The officers, police said, recognized Monat as a man wanted for violating probation. They said he was taken into custody without incident.

After an investigation, police charged Monat with robbery and also ordered him held on the revocation of his probation.

Police said they got calls from several people who said they recognized Monat from surveillance photos of the bank robbery.

Monat is being held without bail at the Cumberland County Jail.
