Butler City Police are monitoring school bus traffic following an incident involving an adult Thursday morning.
According to a press release from the City Police Department, a Valley Lines school bus driver informed police that around 7 a.m. an adult male got onto her bus at Lincoln Avenue near Center Avenue.
The man then used profanity to threaten the students. The driver asked the man repeatedly to leave the bus before he eventually did.
Police were able to use video to identify the man who has not yet been publicly identified. Police believe this isolated event stemmed from a dispute among children that the man decided to get involved with.
