WOODSTOCK, Conn. – Police arrested two Connecticut teens after one allegedly severed a calf’s head and hung it in a school basketball hoop Wednesday.

School officials called the state police around 9 a.m. Wednesday to report someone had dismembered a baby cow and scattered its parts on the campus of Woodstock Academy. The cow’s head was found in a basketball hoop, and its legs were discovered in the ceiling tiles of the boy’s bathroom, though police believe the cow died in a car collision two days prior, WFSB reports.

“When we turned around there was a cow head on the basketball hoop and it was still dripping with blood,” Woodstock student Taylor Littell said. “I got really disgusted especially because the lunch we ended up getting was roast beef, so none of us ate.”

“It’s sick. It’s animal cruelty and nobody should do that especially to a baby calf,” she added.

State police apparently searched student vehicles and recovered a knife they believe was used in the dismemberment, and arrested Avery Blair Rollins, 18, for breach of peace. Rollins was released on a $1,000 bond the same day.

But police also found a machete in another vehicle, as well, and charged Evert McKee, 18, with possession of a weapon in a motor vehicle and breach of peace, though officials do not believe McKee was involved in the cow debacle.

“This weapon is unrelated to today’s incident; it was left in the vehicle from a recent camping trip,” Woodstock officials said, according to NBC Connecticut.

School officials issued a public statement about the cow incident, assuring the public the cow was already dead when it arrived on campus.

“Woodstock Academy has a zero tolerance policy for animal cruelty and weapons, and both incidents have been handled in accordance with said policies,” the statement read, according to the Telegram. “In addition, two students have been taken into custody by the state police. No students were in danger during today’s events.”

State Police Sgt. Shane Hassett told the Hartford Currant officials believe the cow incident was part of a senior prank.

Media reports did not disclose whether the students’ recent criminal charges will affect their graduation, which is scheduled for Sunday, according to The Day.

The cow stunt in Woodstock, however, pales in comparison to an elaborate senior prank at Tennessee’s Sequoyah High School resulted in 100 students banned from graduation, a school resource officer losing his job, and a principal on unpaid suspension.

Around midnight April 30, resource officer James Fisher unlocked the back doors to the school for students with the understanding that they would not vandalize or steal school property. The first wave of students showered the hallways with glitter, balloons, toilet paper and fishing line, but a second wave of students took it to the extreme, WIBW reports.

They dumped out garbage cans and strewed the contents, urinated in the school, spread ketchup and baby oil on the walls, released crickets and chickens, dumped gold fish in toilets, cast hay down the hallways and even left a dead opossum behind, according to the New York Daily News.
