Police say 38-year-old postdoctoral fellow Ben Chun Liu is being held on suspicion of attempted murder and poisoning.

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 UCSF Medical Center and released.

Liu, a Chinese citizen, was placed on an immigration hold and remained in custody at San Francisco County Jail.
Police say they have not determined a motive in the case.
