Lexington, Massachusetts — Lexington police have shut down the door to a Lexington residence in the wake of a threat of a mass shooting at the city’s library.
Officers received a call at about 4:45 p.m. from a person claiming to have a gun at the house, police said.
A security guard then opened the door and spoke to a person inside.
Officers then searched the residence, where they found an AR-15 rifle, a .223-caliber handgun, ammunition and other items, police Chief Thomas Wiedefeld said.
Officers went to the house to find a “suicide vest” and a “bunker jacket,” Wiedefelt said.
A person was arrested, police identified as Anthony Wiebe, 31, of Lexington.
He was charged with possession of an unregistered firearm, possession of ammunition with an unlawful intent and possession of a weapon in furtherance of a drug trafficking offense.
Wiebe was also charged with assault on a peace officer and possession and use of a firearm during a crime of violence.
He will appear in court on Monday.
Wiedefelde said the home is being used as a shelter for evacuees.
The city’s public safety director said the lockdown was in effect.
Police said it was unclear if Wiebes house was the same one that authorities said was used as an attack shelter earlier this month.
