Two Calvert residents have been arrested in connection with a pair of convenience story robberies in Roberston County.

Sheriff Gerald Yezak says 23-year-old Marcus Taylor and 32-year-old Sherman Brown have been charged with two counts of aggravated robbery and that Taylor's also been charged with a probation violation.

Brown turned himself in to authorities Tuesday, while investigators arrested Taylor on Monday afternoon.

On July 30th, the Hearne Food Mart was held-up and Detective Steve Grace with Hearne Police says, the robber pointed a small pistol at the clerk and demanded money and then left with the cash.

On August 5th, during the robbery of the Oak Grove Grocery store four miles north of Franklin, Sheriff Yezak says two female employees were also robbed at gunpoint and that in each case, an undisclosed amount of cash was taken.

The arrests come as the result of a joint operation between the Robertston County Sheriff's Department, Hearne Police and Bryan P-D.

Brown and Taylor both have records in Brazos County. In 2004, Marcus Taylor was charged with burglary of a vehicle and in 2007, Brown faced theft charges.
