ROCHESTER, N.H. (AP) — Police in Rochester, N.H., are looking for one person they think is responsible for three recent armed robberies.

They said the most recent robbery happened early Tuesday at a Cumberland Farms on Milton Road. The store clerk told police a man entered wearing a baggy, blue hooded sweatshirt with white lettering on the front and purple latex gloves.

He showed a handgun and demanded money from the clerk. He fled with some cash.

Investigators said the clothing, suspect, and tactics used in this robbery are similar to two other recent armed robberies. The first happened early Aug. 19 at another Cumberland Farms. The second happened early Saturday at the same Milton Road Cumberland Farms.
