BERKELEY -- A onetime UC Berkeley graduate student instructor was arrested after police say they believe he slipped a substance into a woman's drink and later sexually assaulted her.
Timothy Rodriguez, 40, was arrested Tuesday on suspicion of unlawful sexual penetration and possession of controlled substances, about 2 1/2 weeks after police said he assaulted the woman. UC Berkeley police said the suspect met the 22-year-old college student at a bar near the campus on Jan. 25, and that the two had drinks.
The woman left her drink unattended for a short period of time, then became intoxicated and ill after she returned, police said. Rodriguez then took the woman back to his residence in the University Village at Albany, where police said the alleged assault occurred.
Rodriguez's arraignment was scheduled for Thursday afternoon after he posted his $120,000 bail amount from Berkeley jail earlier in the week.
Police advised students and other adults not leave drinks unattended and to be wary of accepting drinks from people they don't know. They also encouraged using a buddy system while socializing, and advised them to look for signals that a date rape drug may have been consumed. Those signs include dizziness and/or nausea, memory loss, breathing difficulties and trouble moving.
