A school bus driver in Texas has been arrested after threatening to slit the wrists of his passengers.

Bus driver William Allen is alleged to have flipped out after discovering cookie crumbs on a seat, then three 6th graders refusing to confess to the crime when confronted.

According to witnesses, Allen frog marched the kids off the bus, whipped out a two inch blade, and told that he’d slit their wrists with it if they didn’t confess to leaving the cookies.

Police say they confiscated a pocket knife fitting the description after taking Allen, 66 into custody.

According to reports, a school administrator said Allen has been placed on paid administrative leave pending an investigation.
