A postal employee armed with two handguns and an assault rifle shot three state troopers who arrived at his home Thursday to check out a vandalism complaint, state police said.

The troopers fired back, seriously injuring Edward Premo, 40. One of the troopers needed surgery, but all three officers and Premo were expected to recover from their injuries.Two of the troopers arrived at Premo's rented mobile home just before 8 a.m. Thursday after a neighbor accused him of vandalizing her car, according to State Police Col. John Bardelli.

Premo was in the yard when trooper Mark Pelletier and rookie trooper Michael Hoague arrived. Premo shot both with handguns, but the officers were wearing bulletproof vests and able to return fire, police said.

They called for help, and when Trooper James Reidy arrived he was shot in his cruiser with an assault rifle. More troopers followed and Premo was apprehended.
