A male college student in Shanghai jumped to his death from a hall of residence early on Thursday morning, police said.

The 19-year-old freshman jumped from the fourth floor of a dormitory building at Fudan University. The university said he was an exchange student from Yunnan University. The university said it responded to a call at around 1:30 am, and sent the student to hospital within 10 minutes.

Police are investigating the student's death as suicide. A suicide note was recovered from his dorm with a message saying he chose to end his life due to long-term depression, according to microblog posts from his classmates.
