A college student in southwest China's Sichuan Province remains in police custody after he allegedly stabbed his roommate to death on March 27.

Police of Longquanyi district of Chengdu city on Friday confirmed the detention and the incident.

The victim, identified by his surname Lu, was a freshman in Sichuan Normal University. He was stabbed over 50 times and beheaded by his roommate, identified by the surname Teng, around midnight, according to Lu's cousin who was informed of the murder by the university at 1:10 a.m. on March 28.

Lu, born in 1995 in Gansu Province, was raised by his uncle, following his father's death when he was just a toddler.

The cousin said Lu had been outgoing and friendly.

Lu allegedly got into an altercation with Teng on March 26, as Teng objected to Lu singing in the dormitory, but two other roommates helped the two make amends.

Teng left the campus on March 27, and returned to his dormitory late at night, and asked Lu to accompany him to a nearby study room. Teng later returned to the dormitory, asking the other roommates to call the police and went back to the study room and locked the door.

Teng was arrested at the school.

Campus murders resulting from dormitory disagreements in recent years have raised concerns about students' psychological state and interpersonal relationships.

In 2004, Ma Jiajue, 23, a biochemistry student at southwest China's Yunnan University, killed four roommates after what were described as "trivial squabbles."

Another famous case involved a medical student ,Lin Senhao, who poisoned his roommate Huang Yang at Fudan University in Shanghai in 2013.
