US teen on 'vomit assault' charge

Exams are a stressful time for many students

A US high school student who vomited on his Spanish teacher has been charged with battery against a school official.

The 17-year-old from Olathe, Kansas, explained it was an accident brought on by the stress of final exams.

But prosecutors said witnesses alleged the boy intentionally threw up on teacher David Young.

Assistant district attorney Rick Guinn said they were seeking an apology from the teenager, who has since been expelled from the school.

Teacher Mr Young described the incident as "outrageous".

"I think a message is being sent by both the school district and the district attorney that this behaviour will not be tolerated," he told the Associated Press news agency.

The charge of battery against a school official was filed on Monday against the student of Olathe Northwest High School.

The teenager's father said the district had advised his son to enrol in an alternative school at the start of the new school year.
