Prosecutors say a psychiatric evaluation has been ordered for a California woman who was arrested at Philadelphia International Airport after she made threats on board a flight arriving from London.

WPVI-TV reports police arrested Hannah Shiner, of Roseville, Calif., on Wednesday afternoon. Investigators say she threatened the flight crew and passengers, saying she'd blow up the plane. Police have not said what they believe prompted her statements, which the TV station reported including references to Osama bin Laden.

The Delaware County district attorney's office says Shiner faces charges of disorderly conduct and making terroristic threats. Officials with the prosecutors' office tell WPVI that Shiner was arraigned Thursday and is being held on $250,000 bail.

It is not clear if she has an attorney.
