An undercover sting at a McDonald's on suburban Philadelphia's swanky Main Line has led to the arrest of a fast food employee who police say was selling crack at the restaurant.

Officers from Radnor Township Police went undercover four times over the past month at the burger joint located along the 500 block of West Lancaster Avenue in Wayne, Pennsylvania, right in the heart of the town's business district.

Each time, police say they bought the illegal drugs from 29-year-old Allen Trammell, of Philadelphia, in the restaurant's parking lot. A cook at the McDonald's for the past two years, Trammell would leave the kitchen line to deal, officials said.

“When not working as a crew and preparing food, he was out in the rear parking lot selling crack cocaine so in a sense it can give you a new definition of what may be considered a Happy Meal," Radnor Police Lt. Andy Block said.

Officers returned to the McDonald's on Tuesday to arrest Trammell. Police say they found cash and 157 dime bags of crack cocaine packets on him at the time. Block said Trammell could have been grossing $1,500 a week from the illicit sales.

Trammell has been arraigned on $100,000 bail, which he was unable to post. He remains in the Delaware County Prison. Pennsylvania court records show the man has plead guilty to drug possession offenses in 2005.

A spokesperson for the Wayne McDonald's said the franchisee is taking the police matter seriously, but would not comment beyond that.

Radnor Police say they learned about the alleged drug dealing after a confidential informant tipped off its Drug Task Force officers.

An attorney was not listed for Trammell.
