A husband who held his family prisoners in their own home for nearly two years has been arrested, and his wife, mother-in-law and infant son have been freed, police said Friday.

Police spokeswoman Laura Reinsimar said officers acting on a tip believed to be from a neighbor freed the family from their locked and barred home in the San Diego suburb of Oceanside on Thursday afternoon and arrested the husband, Nickolaos Christides, when he arrived home from work.

Reinsimar said the two women and the child, who is 15 months old, were being cared for by relatives in Los Angeles. Christides's wife is 33, and his mother-in-law 83. The two women are believed to be immigrants from Hong Kong. Christides, 59, is a Greek immigrant.
