An automated bomb threat was made this morning (5/27) at Pioneer Elementary School in Bismarck.

This is the second robo-call bomb threat to a Bismarck school this week. Wednesday (5/25), another threat was made at Sunrise Elementary School. That threat and today's threat were fake.

Bismarck Police cleared the building and did a sweep. According to a spokesperson for the Bismarck PD, they treat all threats as real. The call came in at 9:45 and the classes were back to normal by 10:30 a.m.

Several states including Montana and Minnesota received the same threats via robo-call this week.
