Michigan State University and East Lansing police departments have received threats against MSU athletic events.

The departments received letters making general threats, according to authorities.

Both MSU and East Lansing police departments are investigating to determine where the threats came from and if they are credible.

The letters do not give specifics in regards to the threat or particular event.

Students and nearby residents are asked to remain vigilant of their surroundings and report anything suspicious to authorities.

Tensions are high since more than 100,000 people are expected to attend Saturday’s football game against MSU at the University of Michigan.

Larry Young says he hasn’t been to a large public event in 20 years.

“I haven’t felt safe in a public event in a long time,” said Young. “It’s been very scary to go anywhere public with all these crazy people -- And then no gun control”

Tia Tsakos is a former U of M student and is back in town for the game.

“I don’t think it’s really anything that’s crossed my mind but I think I’m just really excited, so I’m in that zone,” she said.

The following email was sent to MSU community members:
