A Japanese man was arrested after a co-worker died in a prank where he allegedly shot compressed air into their buttocks. It happened in the Ibaraki Prefecture Ryugasaki on Saturday.

According to local reports, Yoshiyuki Yoshida, 34 is charged in the accidental death of his 46-year-old co-worker. The pair worked together at a manufacturing plant and were apparently fooling around on a break.

Yoshida reportedly took the air compressor and injected a blast of air in between the man's buttocks. The victim started to feel ill a few minutes later. He was taken to a hospital and died.

Police say the compressor was used over the man's clothing but the force of the pressure is believed to had rushed in with such force that it damaged the man's lungs. An autopsy was planned for an exact cause of death.
