A researcher at UC San Francisco is under arrest after campus police say he poisoned a female colleague’s drink.
Postdoctoral fellow Ben Chun Liu, 38, is being held on suspicion of attempted murder and poisoning, police said.
Investigators who searched Liu’s home and the university urology lab where he worked say they recovered evidence that he poisoned lab co-worker Mei Cao.
Cao was examined at UC San Francisco Medical Center and released.
Liu, a Chinese citizen, was placed on an immigration hold and remained in custody at San Francisco County Jail.
Police said they have not determined a motive for the alleged crime.
