Jamie Lee Lang was back in jail after an undercover sting snared her, for a second time, selling dope.

Jamie Lee Lang received four years probation for running a heroin dealing business from the home where she lived with her two young children. On Wednesday, the Richlandtown woman was back in jail after an undercover sting snared her, for a second time, selling dope. Lang, 29, and alleged accomplice Allen Klein, 53, of Feasterville, were incarcerated on 10 percent of $50,000 bail — $5,000 – following their arrest in Perkasie. Klein was with Lang when she sold 26 bags of heroin for $340 around 4 p.m. to a confidential informant outside the Tidal Wave Car Wash on South Ninth Street, police said. Lang, of 115 East Cherry Street, now faces a possible stint in state prison for violating her probation, said Detective Donald Bender of the Quakertown Borough Police Department, which collaborated on the arrests with the Pennsylvania State Police Bethlehem Troop M Vice Unit.Lang was last busted in an under cover operation on July 19 when police raided her home and found $3,301 and 102 bags of heroin. The raid was prompted after Lang sold $180 worth of heroin on two occasions, June 26 and July 19, to an informant at her home where she lived with her children, then ages 4 and 6. Lang pleaded guilty to drug dealing charges in November and was sentenced on March 14. Bender said the two children are staying with Lang’s mother. Lang and Klein were charged with delivery of a controlled substance, possession of a controlled substance, criminal use of a communication facility and criminal conspiracy.
