ROCHESTER - An anonymous tip to police led to the arrest of a 60-year-old woman for leaving the scene of a head-on crash that injured a Somersworth man.

Beverly Shannon of 28 Periwinkle Drive was arrested Wednesday on a charge of conduct after an accident in connection with a Feb. 2 head-on crash at Columbus Avenue and Summer Street.

Robert Bregy, 50, of Somersworth, suffered injuries police described as not life threatening in the collision. He was driving a 1995 Honda Civic north on Columbus Avenue when a blue Buick, heading in the opposite direction, crossed the northbound lane and hit his car head-on.

The Honda's airbags deployed and the car was substantially damaged in the front. Bregy was transported by ambulance to Frisbie Memorial Hospital for treatment.

The Buick fled the scene, heading north on Milton Road, possibly into Farmington on Chestnut Hill Road. The car also had heavy front-end damage, was leaking fluid from the engine compartment, and had a damaged headlight.

After the crash, police received an anonymous tip from a citizen who identified Shannon as the driver. Investigators located her vehicle and arrested her.
