Indiana University lockdown lifted after police arrest suspects in stabbing

Indiana University issued an "all clear" alert to students early Sunday, after reports of two male students, at large and possibly armed with a knife, forced a four-hour lockdown of its Bloomington campus.

Both suspects are now in custody, Bloomington Police said.

Mark Land, a spokesman for the school, told Yahoo News the incident began at approximately 3:30 a.m. outside an apartment complex where, according to witnesses, three men "met in the parking lot of the apartment building to resolve a dispute when the suspects began chasing victim and wounded him with a knife."

The victim, a 20-year-old student, suffered a knife wound and was transported to Indiana University Health Bloomington Hospital with non-life-threatening injuries.

One suspect, 18-year-old Zesen Shen, was arrested at the apartment complex at 8 a.m. without incident, Land said. Shen was charged with intimidation and battery. Police later arrested 21-year-old Kaiyu Lao, charging him with intimidation. The incident remains under investigation.

Approximately 42,000 students attend Indiana University. About 12,000 live on the Bloomington campus.

Indiana University issued the lockdown alert at approximately 4 a.m., urging students, faculty and staff to lock their doors, avoid windows and remain inside.

The school issued the alerts through email, text messages and social media, including its Twitter feed.
