The Charles County sheriff's office is investigating two armed robberies that occurred within one hour Saturday afternoon at a Waldorf Taco Bell and a nearby Safeway in Smallwood Village. Police said they believe the robberies are related.

About 3:04 p.m., sheriff's officers responded to a robbery at the Taco Bell in the 2200 block of Crain Highway. A suspect had entered the fast-food restaurant and demanded money from the cashier, according to sheriff's office reports. The cashier handed over an undisclosed amount of cash and the suspect fled.

About 3:41 p.m., police received a second robbery report, this time at the Safeway. A man entered a checkout line and demanded money from the cashier, who complied. Again, the suspect fled after receiving the money, police said.

Authorities are seeking the public's help in locating the suspect in both incidents, whom they described as a dark-haired white male, age 35 to 40, with a slim build and tattoos on both arms. He was wearing a red, white and blue polo shirt and jeans, police said.

In one of the incidents, the suspect "implied" that he was carrying a weapon, said Craig Renner, spokesman for the sheriff's office. Renner said he couldn't elaborate on the type of weapon.

Two Waldorf teenagers were arrested Friday in connection with a separate armed robbery attempt on Aug. 5 at Bud's Liquor on Old Washington Road in Waldorf, the sheriff's office reported.

Joseph Ricky Raysor, 17, of Waldorf, was arrested the day of the incident and charged as an adult with attempted armed robbery and related charges. He allegedly walked up to the liquor store's drive-in window carrying a chrome handgun, according to police reports. An employee screamed and ran to the back of the store.

Police stopped a vehicle a short time later and Raysor was arrested when a witness identified him as the gunman, the reports stated. On Friday, the two other occupants of the car--Ronnie Donta Taylor and Shelton J. Barkley III, both 18--were arrested and charged with attempted armed robbery and related charges.
