A military base in Natick remains under a shelter-in-place order Tuesday afternoon following an incident with an on-duty security guard that required a SWAT team response.
Natick Police Chief James Hicks said the situation is “resolved” as of 1 p.m., but the shelter-in-place remained in effect at the U.S. Army Natick Soldier Systems Center, a military research facility.
An incident involving an on-duty, civilian security guard for the base having a mental health episode led to the shelter-in-place, according to Hicks.
The security guard, who was not identified, fled officers when they arrived on base. A hostage negotiator and mental health clinicians spoke with the security guard, and several hours later, he surrendered himself, and he was brought to a hospital for evaluation.
