University of Minnesota Police are asking students to be safe around the Green Line after Metro Transit police report that students are pretending to jump in front of or push others in front of trains.

A public safety alert issued Monday said Green Line operators say they are seeing the "risky behavior" on Thursday, Friday and Saturday nights on Washington Avenue between Huron Blvd. and Church Street.

"LRT Operators understandably nervous, and Metro Transit Police have increased their presence in the area," the alert said.

In addition to being dangerous and "a very bad idea," the acts are illegal and could lead to jail time and a fine, said Deputy Chief Chuck Miner of the University of Minnesota Police Department.

The U's police department issued the advisory at the request of Metro Transit police.
