After a campus lockdown at Indiana University, police said Sunday that they'd arrested two students involved in an early-morning fight.
Zesen Shen, 18, and Kaiyu Lao, 21, are accused of involvement in an altercation outside a campus apartment building that resulted in a 20-year-old student suffering a knife wound, Indiana University Police spokesman William Munroe said.
Witnesses told police that both suspects chased the 20-year-old student, and Shen cut him with a knife in the apartment building's parking lot around 3:30 a.m..
The victim was taken to the hospital with non-life-threatening injuries, school officials said.
Shen was charged with intimidation and battery, and Lao was charged with intimidation, Munroe said.
The altercation sparked a nearly four-hour campus lockdown early Sunday.
The university issued a tweet saying that an "armed individual" was "at large on campus" and that people should take shelter.
Later, campus police issued an all-clear message and said there was no danger to anyone on campus.
