MIDDLEPORT — A Mason, W.Va., man is in custody and Sheriff Robert Beegle said a second suspect’s arrest is expected soon for allegedly robbing a Middleport convenience store at knife point.

Alexander Chandler, 21, Mason, W.Va., is jailed and will be charged with armed robbery, Beegle said, for the robbery of the TNT Pit Stop near Story’s Run. Chandler and another, who remained at large Monday, allegedly wielded butcher knives as they robbed the store clerk of an undisclosed amount of cash. Investigators were able to identify the suspects from a security video, the sheriff said.

After leaving the store with cash, the emotional clerk told investigators, the men left the store in a truck or SUV.

Beegle said the county’s major crimes unit assisted in collecting evidence at the scene, including review of a security tape from the TNT Pit Stop on Ohio 7, resulting in Chandler’s arrest. Chandler is “cooperating” with investigators and arrest of a second suspect is expected soon, Beegle said.

Beegle said the first call from a store clerk came into the Middleport police department just after 10 p.m. on Friday. Lt. Ben Davidson responded first to the call, and shortly after, a store alarm sounded at the sheriff’s department.

The Ohio State Highway Patrol and the Gallipolis Police Department assisted in collecting evidence and searching for Chandler, Beegle said.
