HAMPSTEAD — A “software glitch” prevented police from notifying residents of a standoff on Wheelwright Road Sunday night, Lt. John Frazier said.
A 28-year-old man, whose name is not being released, had reportedly barricaded himself on the second floor of a home at 300 Wheelwright Road and was making threats.
Police were called to the home for a medical emergency at about 9:15 p.m.
The caller told police the man possible had overdosed, was threatening to burn the house down and said he would shoot any officer who tried to enter the home, Frazier said.
Police had been to the house on numerous previous occasions, Frazier said, for “mental health issues” and were familiar with the man.
Hampstead called on police from nearby towns for help locking down the area.
Police tried to send reverse 911 calls to residents in the immediate area to advise them of the situation and urge them to remain indoors, Frazier said, but a programming error prevented those calls from going out.
The Southern New Hampshire Special Operations Unit, of which Hampstead is a member, was activated and a team sent to the scene.
The SWAT team, mental health professionals, doctors and negotiators arrived at the house shortly after 10 p.m., he said.
Negotiations continued for about two and a half hours, Frazier said, at which point SWAT team members entered the home and took the man into custody.
The man was taken by ambulance to a mental health facility for evaluation, police said, and no charges are anticipated.
No weapon was found in the home, according to Frazier.
The vendor for the reverse 911 system, Concord Emergency Management, expected to have everything back online last night, Frazier said.
“They had an issue with it a week ago,” he said. “They found that problem and it created a new problem. It’s a software glitch.”
