MIT Lockdown Called Off After Reports of Gunman Prove Unfounded

Police called off a security lockdown at the Massachusetts Institute of Technology in Cambridge, Massachusetts, this morning after failing to corroborate earlier reports of a gunman in body armor on campus.

A person carrying a long rifle was reported in the Main Group Building, according to a posting on the school’s emergency information website at 9:22 a.m. local time. Students were urged “to stay indoors and shelter in place and report suspicious activity to the campus police dispatch.”

Cambridge police said its officers and those from other law enforcement agencies joined in a search for the gunman.

By midmorning, no one matching the description had been found and the search was called off, according to a tweeted statement by the police.

“Scene is clear. Call unfounded. No threat to public safety,” police said.
