A reward is being offered for information leading to an arrest in last week's armed robbery at People's United Bank.

The Connecticut Banker's Reward Association has established a reward of up to $2,000.

Darien police are continuing to investigate several leads regarding the armed robbery May 1 at People's United Bank in the Goodwives Shopping Center, 25 Old King's Highway North.

According to police, a man entered the bank midafternoon and jumped the teller counter. He pulled out a silver, long-barreled revolver from his waistband and demanded money from two tellers, police said.

No one was injured during the incident. After taking an undetermined amount of cash, he exited the bank and was last seen running toward the rear of the shopping center.

One customer was in an office during the robbery, police said.

Surveillance video shows the man walked into the bank wearing a ski mask and a blue hooded sweatshirt, black gloves and black cargo pants. Police said the man, who they described as 6-foot-3, was using an umbrella to shield his face.

Police are reviewing the surveillance video and working with surrounding police departments as well as the Federal Bureau of Investigation.

It is unknown how the robber arrived at or fled the scene or if he was working alone.

The bank branch has been robbed five times since it opened nearly 20 years ago, according to police.

Darien police are asking anyone who may have seen the suspect to call 203-662-5330.
