A teen suffered a heart attack and was put in a medically-induced coma after a friend squeezed his testicles too hard as a prank, the Irish Mirror is reporting.

The 17-year-old from Dublin, Ireland was on his lunch break at school when a friend approached and "jerked his scrotum." CPR was performed at the scene until emergency medical personnel could arrive.

The teen has been in a coma since last week and is currently in the ICU. Irish police are investigating.
