SAN RAMON -- A pastor at Contra Costa Korean Presbyterian Church has been charged with having an unlawful sexual relationship with a 17-year-old runaway, police said.

San Ramon resident Hyo Bin Im, 33, also known as Pastor John Hyobin and Pastor John Im, was charged by the Contra Costa District Attorney's Office Tuesday with unlawful sexual intercourse, child concealment and animal cruelty, according to a news release from San Ramon police.

Authorities said Wednesday that Im had been hiding two female juvenile runaways at the church in San Ramon as well as at his home in San Ramon.

Calls to the church were not answered.

After Im was arrested, detectives found evidence they said showed that not only did he have a romantic relationship with one of the girls, but that he was responsible for severe animal cruelty that led to the death of a small dog.

Im was arrested and booked into the County Jail in Martinez on Jan. 29, but the jail's automated system did not list him as being in custody Wednesday evening.

Police said Im describes himself as the founder of The Living Well Ministries, a nonprofit organization that Im claims assists emancipated orphans, the homeless and widows. Police said he met at least one of the girls at the Salvation Army Korean Corps in San Francisco.

The investigation is ongoing and anyone with information or additional victims can call San Ramon police Det. Rob Ransom at 925-973-2715.
