Police brought in a bomb squad and closed surrounding streets after a pressure cooker was discovered Thursday morning along the banks of the Muddy River near Kenmore Square, but device was not an explosive, police said.
State Police were notified of the suspicious item at about 11:40 a.m. The Boston police bomb squad was on the scene shortly before noon to secure the device, said State Police spokesman David Procopio. The State Police bomb squad also responded.
Commonwealth Avenue and Beacon Street at Charlesgate were closed due to the scare, along with the Bowker Overpass, State Police said.
The device was disabled at around 12:40 p.m. and all roads were reopened, State Police said.
The pressure cooker did not appear to have been an explosive device, but the incident is under investigation, State Police said.
The Boston Marathon bombers allegedly used pressure cookers to make their two deadly explosives, which killed three and injured 260 others on April 15. Dzhokhar and Tamerlan Tsarnaev also allegedly hurled a pressure cooker bomb during a confrontation with police in Watertown several days after the bombings.
Tamerlan Tsarnaev was killed during the confrontation. Dzhokhar Tsarnaev faces federal charges that could bring him the death penalty.
