A Warren man was charged in federal court with distributing heroin and crack cocaine and maintaining a drug house.

Robert J. Lang, Jr., 24, was arrested Tuesday.

The U.S. Department of Justice said Lang sold gram quantities of heroin and cocaine between February and June of this year. 

He also used 1030 Mason Street in Warren as a place to sell and store drugs, according to an affidavit filed in the case.

Law enforcement agents from the DEA, TAG Law Enforcement Task Force, and ATF searched the Mason Street house in March and found approximately one ounce of heroin and one ounce of crack cocaine, as well as surveillance equipment, syringes, Narcan, a money counter and an assault rifle magazine, according to the affidavit.

This case was investigated by the Drug Enforcement Administration, the TAG Law Enforcement Task Force and the Bureau of Alcohol, Tobacco, Firearms, and Explosives.

It is being prosecuted by Assistant. U.S. Attorney David M. Toepfer.

If convicted, Lang's sentence will be determined by the Court after review of factors unique to this case, including his prior criminal record, if any, his role in the offense and the characteristics of the violations. 

In all cases, the sentence will not exceed the statutory maximum and, in most cases, it will be less than the maximum.
