A USC professor was fatally stabbed on campus, allegedly by a student who was subsequently arrested, Los Angeles Police Department Officer Drake Madison said.
Cops were called to a report of a stabbing in the 3600 block of McClintock Avenue at 4:35 p.m., he said. The street runs through the USC campus. "The victim in this was a professor at the university," Madison said.
Paramedics were called to the scene one minute earlier, Los Angeles Fire Department spokeswoman Margaret Stewart said. The victim was found dead at the scene, she said.*
"The suspect was a student," Madison said. He's in custody, he said.
A news conference was expected to take place tonight.
UPDATE at 9:58 p.m. Friday, Dec. 2, 2016: In a letter addressed to the USC community, university President Max Nikias identified the victim as Bosco Tjan, a professor of psychology in the Dornsife College of Letters, Arts and Sciences, who also served as co-director of the Dornsife Cognitive Neuroimaging Center.
Nikias said Tjan joined USC in 2001 as an expert in perception, vision and vision cognition.
The attack took place in the Seeley G. Mudd building, and public safety security officers quickly apprehended a student suspected of the violence, the president said.
"As the Trojan Family mourns Professor Tjan’s untimely passing, we will keep his family in our thoughts," Nikias wrote. "We encourage anyone in need of support to reach out to Student Counseling Services or the Center for Work and Family Life."
