A drugstore clerk faces a grand larceny charge after stealing more than $5,000 worth of prescription drugs from the Valley Stream store's pharmacy, police said.

Muhammad Ahmer Khan, 19, of 168 Green Acres Rd., removed a number of drugs -- including oxycodone, methylphenidate, hydrocodone and amphetamine salts -- from Dale Drugs on West Merrick Road in Valley Stream between Aug. 1 and Aug. 25, Nassau County police said Friday in a news release.

The Narcotics Vice Squad arrested Khan Thursday afternoon and charged him with one count of third-degree grand larceny.

Maria DeVivo, the owner of Dale Drugs, said Kahn was hired in January. Her staff began to notice large discrepancies in their drug stocks while doing inventory in early August.

"We keep a tight control on our drugs," she said.

The staff reviewed security camera footage that showed a man who appeared to be Khan, who had not been cleared to enter the pharmacy, removing pills from bottles and putting them in his pockets, DeVivo said.

The video footage was turned over to police, she said. Khan was fired Thursday, the same day he was arrested, DeVivo said.

"We're just surprised by it," said Saima Kahn, Kahn's mother, adding that her son will work with an attorney and go through the legal system.

It was not immediately known whether the pills were recovered by police.

Khan was arraigned in front of Judge James Darcy at First District Court in Hempstead Friday. He was released on his own recognizance and is due back in court on Sept. 9.
