According to the Bismarck Tribune, Tuesday evening, Wal-Mart called the Bismarck Police Department after the store received a call stating a bomb was in the store.

Once again, police searched the store and found nothing.

This was the second time in less than a week that the store had a bomb threat, and the second time, it was a dud. The same incident happened Monday.

According to reports, the person calling the store was a male.

The store was cleared in less than 30 minutes.
