A man dressed as a Wells Fargo guard entered Makro, a distribution outlet in Largo, and walked away yesterday with a "substantial" amount of money, Prince George's County police reported. Investigators said, however, that two suspects were arrested shortly afterward as they drove on the Capital Beltway, and all the cash was recovered.

The suspects were identified as Morris Artis, 29, of Northwest Washington, and Raymond C. Ferrell, 32, of Alexandria. Officers said they were charged with felony theft and the concealment of a deadly weapon. Artis also was charged with impersonating a security officer.

Police spokesman Capt. David Mitchell said that a man dressed as a guard walked into the store, an establishment that sells food and other merchandise on a members-only basis, shortly after noon and showed bogus identification to an employe before he obtained money. Store officials refused to comment.

Mitchell said the unidentified employe became suspicious and followed the man from the store and saw him leave -- not in a Wells Fargo truck, but in a yellow Pontiac. Police would not disclose the amount of money taken, but said that all of it was recovered from the car they stopped near St. Barnabas Road.
