One ingredient did not belong in the burrito that Deputy Henry Marin allegedly agreed to deliver inside the Los Angeles jail: heroin.

The 27-year-old, who worked at the Airport Branch Courthouse in Los Angeles, has pleaded not guilty to two felonies: bringing drugs into a jail and conspiracy to commit a crime.

Marin conspired with three people, one whose identity is still unknown, to bring heroin into the Airport Courthouse in February 2010, according to the indictment.

On Feb. 23, 2010, Marin "poked his head outside Department A" and waved for his conspirator to come meet him, the indictment states. It claims he asked her if she was "for Alvarez."

She handed him the burrito and explained the heroin was inside, according to the court document.

"Okay…no problem," Marin allegedly told her and took possession of the burrito.

He pleaded not guilty to the charges Wednesday and was released on $25,000 bail.

This isn't the first time the heroin-in-the-burrito trick has been pulled.

In 2006, Rosemary Gonzales was caught smuggling heroin inside of a burrito while trying to enter a New Mexico detention facility.
