This was a prank of epic proportions. Where did they even get 72,000 ladybugs from? 

Police have charged seven suspects in a senior prank that released 72,000 ladybugs in a public high school.

The St. Mary’s County’s Sheriff’s Office says in a news release that early May 20, five people forced open a door at Chopticon High School in Morganza, Maryland.

Deputies say the pranksters, who were wearing masks and hoodies, released a swarm of ladybugs throughout the school while two others waited in a car.

Six Chopticon senior students and one alumnus allegedly broke into the school at around 3:30 a.m. Wednesday and released the lady bugs inside, MyFoxDC.com reported. Now they are facing criminal charges.
