Updated with info from the MBTA, including the fact the device was a sterilizer, not a pressure cooker.
The Bradford stop on the Haverhill Line was shut for two hours today as police investigated what turned out to be a sterilizing device just sitting there. A spokesman says:
There was no explosive device found. It was a sterilizer type device, not a pressure cooker, and was empty. It was placed near the trash bin. The MBTA Transit Police Explosive Detection Unit responded to the scene and inspected the item to make sure it was safe. Transit Police worked in conjunction with Haverhill Police and Fire Depts. Two commuter rail trains were affected by the incident that lasted approximately 2 hours.
