Authorities locked down the Maryland State House in Annapolis late Thursday afternoon, instructing occupants to shelter in place.

The Maryland Department of General Services released a statement after the lockdown was lifted.

“This afternoon, the Annapolis City Police Department received a call from an individual threatening to target the Maryland State House.

“The Annapolis City Police immediately notified the Maryland Capitol Police, Maryland State Police, Anne Arundel County Police, and security personnel in the House and Senate buildings about the potential threat. Within minutes of receiving the information, Maryland Capitol Police placed the Maryland State House, Government House, and House and Senate Office Buildings on lockdown, directing occupants to follow instructions from law enforcement – including to shelter in place.

“The Maryland Capitol Police coordinated sweeps of the State House, Senate and House buildings and surrounding grounds, according to protocol, and determined that the areas are secure and clear of any potential threat. The lockdown and shelter in place was lifted at 6:52 p.m. and all remaining occupants, including the governor, lieutenant governor, and senate president, were escorted from the building, per situational protocol. State House grounds have resumed standard security procedures and protocol.”
