Local, state and federal law enforcement agencies participated in the investigation that ended in a raid in May 2014. The Frederick County Sheriff’s Office says the Iqbals were arrested after authorities seized more than $100,000 worth of synthetic marijuana from their three gas stations and their home in Thurmont.
