Varun Manish Chheda, a 20-year-old Indian-American student at US's Purdue University, was killed in his dorm room by his roommate, who has been arrested on a preliminary murder charge, police said.

Ji Min Sha, a 22-year-old junior cybersecurity major from Seoul, South Korea, has been held as the prime suspect in the case, Purdue Police Chief Lesley Wiete said. Wiete called the crime "unprovoked and senseless".

Chheda died of "multiple sharp force traumatic injuries" and the manner of death was a homicide, according to preliminary autopsy results, an NBC report said.

A university spokesperson told the media that a 911 call came into the Purdue University Police Department at 12:44 a.m. on Wednesday from McCutcheon Hall on the western edge of the campus.

The call was made by Sha himself. Purdue University President Mitch Daniels said in a statement that the Purdue University Police Department is conducting a thorough investigation into the incident.

"This is as tragic an event as we can imagine happening on our campus and our hearts and thoughts go out to all of those affected by this terrible event... I assure you that the safety and security of our students is the single highest priority on our campus," Daniels added in his statement.

This was Purdue's first on-campus homicide since January 2014, according to the University.

Chheda was just 10 days away from his 21st birthday, the Indianapolis Star reported.
