Montgomery County police have arrested a Southeast Washington man in connection with break-ins at two gun shops last year.

Charles K. Duvall Jr., 19, of the 4800 block of Alabama Avenue, was charged Wednesday with one count of burglary stemming from an Oct. 18 burglary of a Wheaton gun shop. About 70 weapons, including high-powered shotguns and semiautomatic pistols with a total value of more than $40,000, were stolen from Guns Unlimited in the 2300 block of Price Avenue, police said.

Duvall also is charged with one count of burglary in connection with a Nov. 3 theft of five to seven handguns from Atlantic Guns in Silver Spring, a Montgomery County investigator said yesterday.

According to court documents, Duvall was charged by D.C. police on Dec. 5 with possession of a handgun allegedly stolen from Atlantic Guns. A Montgomery detective said D.C. police made that charge after taking a .45-caliber automatic pistol from Duvall when he was arrested on disorderly conduct charges.

In the Wheaton break-in, the burglar removed a vent cover on the roof of a restaurant and punched a hole through the drywall separating the restaurant and an adjoining antique shop, according to court documents. Once inside the antique shop, the burglar smashed through a wall into the gun shop, police said.

A Montgomery detective said police have recovered five weapons stolen from Guns Unlimited, as well as a stolen handgun allegedly used in a drive-by shooting in the District.

In November, District police seized three weapons stolen from the Wheaton shop during a drug raid in Northwest Washington. Two shotguns and a handgun taken from Guns Unlimited were among a cache of 14 weapons recovered by police, a District detective said.

Montgomery police said Duvall was first extradited to the county on Dec. 10 on a warrant in the Atlantic Guns burglary and then released on a $2,500 bond. Based on new information, he was extradited again to Montgomery on Jan. 4 on a warrant in the Guns Unlimited burglary. Duvall is held now in the Montgomery County Detention Center in Rockville.
