OXNARD, Calif. (AP) — A court filing by Amanda Bynes' parents says they are "deeply concerned" that their actress daughter is a danger to herself and others, and she needs to be placed in a conservatorship.

Friday's petition by Richard and Lynn Bynes says their daughter has expressed fears she's being watched by smoke detectors and devices in her car's dashboard.

A judge has delayed ruling on the petition.

The 27-year-old actress was placed on an involuntary psychiatric hold Monday after authorities say she started a fire in the driveway of a home in the Los Angeles suburb of Thousand Oaks, where she grew up.

The hold has since been extended.

The Byneses' petition cites their daughter's arrests in recent months and concerns about her spending as additional reasons a conservatorship is necessary.

A California judge delayed making a decision Friday on whether former child star Amanda Bynes should be put under the conservatorship of her parents.

Ventura County Superior Court Judge Glen M. Reiser said there was no rush to act on the request by Bynes' parents because the actress is under a two-week psychiatric hold at a hospital.

Reiser scheduled a hearing on the issue Aug. 9 and said he also wants to meet one-on-one with Bynes before making a decision.

The 27-year-old actress' behavior has become increasingly bizarre over the past year.

Bynes was put under the psychiatric hold Monday after authorities said she set a fire on the driveway of a home in the Los Angeles suburb of Thousand Oaks, where she grew up.

In May, Bynes was arrested in New York for allegedly throwing a marijuana bong out the window of her 36th-floor Manhattan apartment. Police had come to the apartment to investigate a complaint that she had been smoking marijuana in the building's lobby.

Last year, Bynes was charged in Los Angeles with driving on a suspended license, the license having been suspended after she was charged with driving under the influence and misdemeanor hit-and-run.

Bynes, who was only 13 when she landed her own hit variety program, "The Amanda Show" on the Nickelodeon cable network, went on to star in the TV series "What I Like About You" and several movies, including "What a Girl Wants," ''Hairspray" and "She's the Man."

Her career has declined in recent years, and the Internet Movie Database lists her last film credit as 2010's "Easy A," which starred Emma Stone.
