New Jersey state troopers have arrested a woman who allegedly had 333 packets of heroin stuffed in her bra.

Kim Decker, a 54-year-old woman from Montague, N.J., was pulled over on Route 80 Monday after police spotted her driving erratically, The New York Daily News reports. Neither Decker nor her passengers had a valid driver’s license, so the investigating officer decided to impound her Honda Accord.

When Decker and her passengers exited the vehicle, police noticed a “wax fold,” an apparatus commonly used to store drugs, within the car. When questioned about the fold, Decker admitted that she was carrying heroin in her person, and gave police permission to search her Accord.

After a strip search at the nearby Netcong barracks, a female officer discovered a total of 333 packets of heroin stuffed in her bra, The Daily Mail reports. Troopers also discovered drug paraphernalia hidden in her vehicle, reports.

Decker was booked and charged with possession of heroin with intent to distribute. She is being held at the Morris County Correctional Facility on $50,000 bail.

A second passenger, 51-year-old Ernest Broadwell, was also charged with possession with intent to distribute and released with a court date, The Daily News reports. The vehicle’s third passenger was also arrested, but the charges against him have yet to be revealed.

Decker has had multiple brushes with the law. In 2006, the 54-year-old was arrested for driving with a revoked license, the Daily Mail reports.

This isn’t the first time that a female suspect has used an undergarment to conceal illegal drugs. Earlier this week, a 30-year-old California woman was arrested after admitting that she was carrying a bag of cocaine in her bra, local television station KGBT-TV reports.
