LOS ANGELES (CBSLA.com) — Authorities say a 27-year-old man convicted of raping two women he met at a café was sentenced Thursday to 30 years to life in prison.

Andrew Van Bui of Monterey Park was also ordered to register as a sex offender for life, the Los Angeles County district attorney’s office said in a written statement.

The prosecutor assigned to the case said Bui met the victim at the café where he worked.

The first victim, a 26-year-old woman, was drugged and sexually assaulted at Bui’s home, the prosecutor said. That incident occurred in August 2013.

A week later, authorities say Bui met a second woman, age 22, at the same café and invited her to his home, where she was sexually assaulted.
