Bush's niece found with cocaine

President George Bush's niece has been found with cocaine at a Florida rehabilitation centre.

Police said Noelle Bush, 25, was undergoing drug treatment there.

They were called to the Centre for Drug Free Living in Orlando where workers gave them a substance they said they found on her.

Noelle is the daughter of Florida Governor Jeb Bush, the president's younger brother.

The workers told police that the two grams of powder tested positive for cocaine, but police did not immediately arrest her because they couldn't obtain a sworn statement that she was in possession of cocaine, said police Sergeant Orlando Rolon.

The investigation will continue, said Rolon, who added that police had yet to interview Noelle.

She was arrested in January at a Tallahassee chemist's drive-through window for allegedly trying to buy the anti-anxiety drug Xanax with a fraudulent prescription.

In July, she was found to be in contempt of court because a worker at the treatment centre found her carrying prescription pills. A judge sent her to jail for three days.
