After being involved in a disturbance last night in Thousand Oaks, Calif., Amanda Bynes is being detained for a mental health evaluation, a Ventura County Sheriff's Office spokesman has confirmed to ABC News.

The 5150 involuntary hold allows a qualified officer to confine a person for 72 hours who is deemed to have a mental illness that makes them a danger to themselves or others.

The statement said deputies investigated the incident, which took place in a residential neighborhood, and determined that Bynes, 27, met that criteria. The nature of the incident was not described.

Bynes was in an New York court earlier this month for charges of reckless endangerment, tampering with evidence and marijuana possession, following a May arrest.

The "Easy A" star was arrested after allegedly throwing a bong out of her apartment window. The hearing for that case was postponed until late September.
