A homemade bomb hidden inside a soda bottle exploded in a school playground in Montana on Tuesday.
Lewis and Clark County Sheriff’s Office claimed there were no injuries at Rossiter Elementary School in Helena but they evacuated the building as a precaution following the discovery of the improvised explosive device, (IED).
School officials blocked off the area and phoned police minutes before classes began for the day around 8.20 am.
The IED was described by authorities as a soda bottle type device that had been covered in duct tape.
No threat had been made, authorities said, and no damage to the building was reported.
All Helena District 1 Schools and East Helena Schools remained on lockdown on Tuesday as a thorough search was conducted.
In a Facebook post, East Helena School District 9 said: ‘After an exhaustive search of the school grounds in East Helena by the East Helena Police and the Lewis & Clark County Sheriff’s Office.
‘The District has been cleared to lift the lockdown of the schools. The District will remain cautious as the Sheriff’s Office continues their investigation.’
Sheriff Leo Duttontold ABC News they are not sure exactly when the device exploded, saying it ‘was in a pop bottle.’
He said: ‘It was a pop bottle that had been out on the playground and it had some definitive marks about it.
‘It was covered in duct tape, but we’re not releasing the exact components, but it was an IED.’
‘What precautions have been taken so far is all of the kids in Rossiter school are out for the day, they were given a safe evacuation route over to the little red schoolhouse.
‘We called in the FBI and ATF, our bomb squad is there and we’ll be using a bomb detection dog to clear the area.’
