Officials say more than 100 people were arrested on drug offenses during a two-day sting by law enforcement agencies that also targeted gun and human smuggling operations in the Houston area. Harris County Sheriff Adrian Garcia said Monday that officers stopped more than 900 vehicles during last week's operation along Interstate 10 and U.S. Highway 90. From those traffic stops, officers made arrests and seized more than 5 pounds of cocaine, 11 pounds of marijuana and three stolen guns. Garcia said Houston is a major distribution hub for drugs, guns and human smuggling and officials are hoping that similar initiatives will disrupt trafficking operations. Last week's operation included the Drug Enforcement Administration and the Texas Department of Public Safety.
