A man involved in a police standoff in Dixmont is in critical condition after being shot by officers.

The man, Michael S. Grendell, 61, barricaded himself inside his home yesterday and refused to come out, according to police spokesman Steve McCausland. The standoff lasted overnight, firing several shots this morning that struck the State Police Department's armed vehicle and robot. No officers were injured. An ambulance arrived just before 10 a.m. Friday, and police say Grendell is being treated for injuries sustained as the standoff ended.

Three officers were involved the shooting. Sergeant Christopher Harriman, Trooper Caleb McGary and Trooper Andrew Hardy are on paid administrative leave while the incident is investigated. That is protocol.

The incident started when State Police were called to the home for a report of shots fired. They say that there's been an ongoing dispute between neighbors there and that someone reported hearing gunfire.

State Police troopers were joined by members of the tactical team, negotiators, and members of the bomb team. A tactical team from New Hampshire was en route but was called off before they arrived in Dixmont.

Grendell was arrested on charges of Reckless Conduct with a Dangerous Weapon, Criminal Threatening, and may face other charges as the investigation is completed and prosecutors are able to review the facts.
