CHELMSFORD -- The hunt for a 24-year-old man spurred officials to place Nashoba Valley Technical High School on lock-down for about an hour Thursday, according to a press release.
The lock down has been lifted, though the search for the man continued, according to the release from Chelmsford Police sent shortly before 2 p.m. the same day.
"The lockdown was lifted and officers are actively searching the area for the man, but at this time, do not believe the community is in any danger," according to the press release.
Chelmsford Police responded to Chelmsford Commons, a mobile home park on Littleton Road, for a report of a disturbance involving the 24-year-old Chelmsford man.
Spokeswoman for the department, Jessica Sacco, declined to further describe the incident. She said the suspect was described as a white man wearing black sweatpants and a black sweatshirt.
By the time officers arrived, the man had fled, according to police. The man, who was not named, has an unrelated warrant for his arrest out of Lowell District Court related to motor vehicle related charges, the release said.
Police initially believed the man could have been armed with a firearm, prompting the lockdown "out of an abundance of caution," according to the press release.
Police later learned he may be in possession of a bb gun, not a firearm, according to the press release.
In a statement, Nashoba Tech Superintendent Denise Pigeon said: "There was an incident in Chelmsford and at the request of Westford PD we did go into a shelter-in-the-building mode as a precautionary measure and secured our exterior perimeter. Classes went on as normal here in the meantime and an all-clear was issued once Chelmsford PD contacted us."
