A senior prank in which 72,000 ladybugs were released in a public high school has several youths and adults facing criminal charges.

Early Wednesday, five people forced open a door at Chopticon High School in Morganza, Maryland, according to the St. Mary's County's Sheriff's Office.

Wearing masks and hoodies, they released the ladybugs throughout the school while two others waited in a car, deputies said.

Four male juveniles and three men were identified as suspects, investigators said. One of the suspects ordered the ladybugs online, deputies said.

The four juveniles are charged with burglary, property destruction and disruption of school activities. They were released to their parents.

The three men will be charged by criminal summons, deputies said.
