Troubled singer Amy Winehouse's dad Mitch is seeking to have the star committed to a mental institution, because he is convinced this is the only way he can save his wild daughter from her alleged drug demons.Mitch is so desperate for the Grammy-winner to live a clean and sober lifestyle, and has grown increasingly worried over her erratic behaviour, which resulted in her arrest and subsequent police caution over accusations of assault earlier this week. And now Mitch wants his troubled daughter to be sectioned under the U.K.’s Mental Health Act, because she has proven she is at risk of hurting herself and others. He tells British newspaper the News of the World, "I want her sectioned. The situation is getting out of control. I want her off the street. I don’t think being somewhere (in rehab) for six weeks is going to cure her problems. I think it needs far more radical measures."I’ve been on the phone to Amy’s manager in Los Angeles and he’s starting things rolling. They are going to be speaking to doctors, psychologists and everything else. Ultimately, it’s the doctors who will decide if anybody is sectionable."I’ve told them (medical authorities) she is a danger to herself. There is evidence of self-harming and she’s a danger to other people because she’s attacked someone."Obviously as her dad I will try and do what’s best for her. Unfortunately, what I think is best for her and what she thinks is best for her are two different things."
