Boston Police detonated a suspicious device discovered by a local bar owner on Western Ave. in Brighton early Monday evening.

Conor Hoey, who runs The Boyne Irish Pub, said he discovered the device about 25 feet from his restaurant and quickly alerted a nearby police officer.

“I saw a wire hanging out of it,” he explained.

Hoey said police told him the device was an abandoned pressure cooker, adding that police used a water cannon to discharge the device.

One witness on Twitter reported hearing "a massively loud" explosion.

"[An] officer said the pressure cooker appeared empty, but 'we blow 'em up anyway' (controlled) to be safe," @maffematician tweeted.

The restaurant was closed for approximately an hour and a half, but re-opened Monday night, Hoey said.

An email and phone call to the Boston Police Department for further information was not immediately returned, but we’ll update the story as official information is made available.
