BRUNSWICK — A man who disguised himself in a safari-style hat known as a pith helmet and a tan neck warmer that covered his face was arrested Tuesday on a charge of robbing a Brunswick bank at gunpoint last week.

Brunswick Police Department Detective Sgt. Martin S. Rinaldi said in a news release that Brunswick police, with assistance from the FBI and Maine State Police Crime Laboratory, were able to identify the suspect, 20-year-old Benjamin Lamphere.

Rinaldi credited bank security measures and “detailed teller observations” for enabling them to locate Lamphere.

Lamphere, who lives on Perreault Way in Brunswick, was charged with Class A robbery. Lamphere allegedly walked into the Bank of Maine branch at 137 Maine St. on Feb. 18 at 2:06 p.m. He displayed a handgun before fleeing in a Saab with an undisclosed amount of cash.

Lamphere is being held at Cumberland County Jail in Portland on $20,000 cash. He is scheduled to appear in court on April 21.

The investigation is ongoing and police are still working to collect evidence from various locations throughout the state.
