Shelter in place lifted at US Army facility in Natick, Mass.

A shelter in place at Soldier Systems Center Natick in Massachusetts has been lifted after more than two hours. Personnel were asked to remain on the base.

“Personnel may resume normal operations on base,” the center said in a post on its Facebook page. “At this time, all personnel are required to remain on the installation and away from the gate until further notice. We will continue to monitor the situation and provide updates and instructions as they become available. Thank you for your cooperation.”

Local channel WCVB 5 reported, citing Natick Police Department Chief Jim Hicks, that police were called to the facility for a possible distressed individual. The man, working as an armed security guard, was taken for a medical evaluation after a SWAT team responded.

The center is a military laboratory charged by the Defense Department with the research and development of food, clothing, shelters, airdrop systems, and other support items for the U.S. military.
