FARMINGTON — Police on Friday obtained an arrest warrant for the man they believe robbed the TD Banknorth branch on Broadway on Dec. 12.

Kevin E. Lunn, 38, a transient from the Bath/Brunswick area, is wanted on a single count of Class A robbery, Farmington Police Chief Richard Caton said.

“He’s still out there; he’s not in custody,” Caton said.

Police in December said a man entered the Farmington bank during a busy part of the afternoon and demanded money, telling the teller he was armed.

No firearm was displayed, according to police.
