When a woman who had tried to commit suicide by drinking rat poison was rushed to hospital on Tuesday, doctors discovered a lock around her private parts.
Her husband, who works as a mechanic, admitted that he drilled holes into her at home four years ago. Every morning, before leaving for work, he would insert the lock, taking his key with him.
The couple had been married for 19 years and has five children.
The mechanic has been arrested for cruelty and for voluntarily hurting another person. He said he wanted to ensure that unlike other women in his family, his wife would not "betray" him.
