Milford police have arrested a man they suspect of robbing Milford Bank on Bridgeport Avenue in January. An investigation into the robbery led police to John Dearborn, 46, of Manchester as a suspect. Investigators secured an arrest warrant for Dearborn, and arrested him July 30. Dearborn was already incarcerated with the Connecticut Department of Corrections for a prior arrest. Milford police charged him with robbery, larceny and breach of peace. He was arraigned in court and held on a $250,000 bond. On Jan. 14, the Milford Police Department received a complaint of a bank robbery at the Milford Bank located at 205 Bridgeport Avenue in Milford. A preliminary investigation that day revealed that a man entered the bank, walked up to a teller and placed a paper bag on the counter, indicating it was a bomb. The man handed the teller a note and the teller complied with the demands and handed over money. Upon leaving the bank, the man left the bag that he indicated was a bomb at the teller station. The bank and buildings surrounding the bank were evacuated as a precaution and vehicle traffic was diverted away from the scene. The Connecticut State Police Emergency Services Bomb Squad assisted with the investigation and determined that there were no explosives in the package.
