Police are searching for a man who robbed a Citizens Bank on Indian Rock Road and fled on foot with an undisclosed amount of cash on Tuesday, Oct. 7.

The suspect, described as a white male in his mid-20s, 6 feet tall with a slim build and bright blue eyes, handed the bank teller a note demanding the money at about 9:15 a.m. Police said he did not display a weapon during the robbery.

“Only one teller knew there was a robbery going on. She was understandably shaken up,” said Windham officer Carl Wagner. “She acted according to her training.”

He described her as a “composed and good witness.”

State and local police continue to search for the suspect, described as wearing a gray Northface zippered sweatshirt with no hood, jeans and a gray knit cap with a dark stripe around the edge. He was last seen leaving Citizens Bank heading toward a McDonald’s restaurant across the street by the Interstate 93 Exit 3 northbound on-ramp. Police said the bank robber took a hard left back behind the bank and moved parallel to Route 111 West while in the woods.

Bank officials told the authorities that the money he was handed included a dye pack which should have exploded within a short distance of the bank. Police said later that day that they had located the dye pack along the northbound onramp and they believe the suspect may have the red dye on their body and clothing.

A K-9 unit with the state police tracked the robber’s trail to the former Dunkin’ Donuts building about a quarter of a mile west of the bank. Police said the suspect may have had a vehicle already parked there or he may have been given a ride, although authorities believe there was only one person involved in the robbery.

Police said they believe the suspect headed north on I-93 in an unknown vehicle.

Windham police will continue to investigate the crime along with the state police and the Rockingham County Sheriff’s Department. Other area police departments had also been made aware of the robbery. While the FBI office in Portsmouth was also alerted to the situation, they will not be participating in the investigation.

This is the first bank robbery in Windham in three years, Wagner said. The last one occurred at the same Citizens Bank and had recently been solved.
