Sheriff’s officials were searching Sunday for a man convicted of stalking actress Mila Kunis after he escaped from a mental health facility in Pomona, officials said.

Stuart Lynn Dunn made an unauthorized departure Saturday around 8 p.m. from a secured mental health facility in Pomona where he was being confined to post-release supervision, Los Angeles County Sheriff’s Department Lt. Martin Rodriguez said.

Dunn was previously convicted of stalking Kunis, when he allegedly violated a restraining order by repeatedly trying to contact the “Black Swan” actress and temporarily lived in a vacant home she owned, the Los Angeles Times reported in 2012.

The Los Angeles County Probation Department contacted the Sheriff’s Department’s Major Crimes Unit Sunday asking for assistance in locating Dunn.
