Grace Lilly Arrested for Drug Possession

 Grace Lilly's arrest in Charleston, South Carolina last week came after authorities determined she had illegally possessed a dozen clonazepam pills.   

The star, 27, was taken into custody on March 10 in connection with possession of a controlled substance, legal documents obtained by the Los Angeles Times revealed.

On Monday, law enforcement in Charleston said testing conducted by Charleston Police Department’s Forensic Services Division revealed it to be clonazepam, which is a Schedule IV controlled substance.

Lilly initially told police she believed the pills were birth control, authorities said. After the results of the test were received, a new warrant was issued for the arrest of the Bravo star.

Lilly last week was taken into custody - marking her second arrest in three months - and subsequently released on $10,575 bond, according to legal documents.
