In a prank played by a friend, a person playing cards jumped from third floor and died later. When a group of friends playing cards on the third floor of a house, suddenly a friend shouted 'police'. Fearing for the worst, a person in the group playing cards jumped from third floor, fell on insulated electrical wires and then on the ground. Though, there were no visible external injuries, the person died due to internal injuries while undergoing treatment.
Such pranks or horse play anywhere are dangerous, particularly in shop floor areas and shop floor in-charges have to warn all employees particularly those who are fresh from school/college as their awareness about workplace hazards is poor.
