The Amigos School in Cambridge was placed on lockdown and Andrew Street was closed for about an hour Monday afternoon while police investigated reports of a man who was suspected to be carrying weapons in the area, Cambridge police said.
Police first received reports that a white male wearing cargo pants and a dark-colored hoodie was in a residence on Andrew Street with a gun and a knife around 2:30 p.m., said Cambridge police spokesman Jeremy Warnick.
The lockdown was lifted and officers cleared the scene at 3:59 p.m. after locating the man who was the subject of the report inside the home, Warnick said.
They determined the man was not a threat and the incident was not criminal in nature, Warnick said. The man was transported to a local hospital for a mental health evaluation.
No injuries were reported, but Warnick said issuing a shelter-in-place warning is a rare occurrence in Cambridge.
“We have to treat any of these reports seriously,” he said. “This is a unique event.”
