Troubled actress Amanda Bynes has been placed on involuntary psychiatric hold here, reports tmz.com.

The 28-year-old will be held for 72 hours, but it could be extended to 14 days as her parents move to get a conservatorship over her.

Bynes was reportedly driven to the Pasadena hospital after she came to Los Angeles from New York, while she believed that she was heading to meet her attorney at The London Hotel.

Her admission into rehab has come after she made some serious allegations about her father on Twitter.

Bynes had claimed that her father "verbally and physically abused" her as a child. But she later took back the allegations, saying: "My dad never did any of those things. The microchip in my brain made me say those things but he's the one that ordered them to microchip me.`
