Fairfax County Police Department (FCPD) reported the arrests of Edward Raul Mejia Sandoval, 22, and Manuel Enrique Casco, 34, both of Maryland. They were arrested after robbing a local business shortly after 7 p.m. on Sept. 2 in the 700 block of Elden Street in the Town of Herndon, according to police reports.

According to FCPD, Mejia Sandoval was charged with two counts of robbery and two counts of threatening to abduct with the intent to defile; Casco was charged with robbery, carjacking and two counts of use of a firearm in the commission of a felony. Both men were taken to the Fairfax County Adult Detention Center and held without bond.

Police reported detectives from their Major Crimes Bureau are investigating after Mejia Sandoval and Casco entered a business displaying a handgun, demanded money and assaulted two female employees.

According to a briefing given by Chief Maggie DeBoard, Town of Herndon Police during the Town of Herndon Work Session held Sept. 3, an officer was sitting in his cruiser doing follow up paperwork behind the fire station at that time. "There was an armed robbery that had just occurred, up in one of those businesses in that area," DeBoard said. She added there were two victims in the business.

"[One] noticed that the officer's cruiser was parked outside through a security camera and was able to run down and alert the officer … the officer immediately engaged them," said DeBoard. She said that the officer got in a foot pursuit with both subjects. "As he was chasing the subjects, giving them verbal commands, one of the suspects actually turned and fired rounds at our officer and our officer returned fire back. Nobody was hit thankfully either way, which is always a good thing."

FCPD reported Mejia Sandoval was quickly taken into custody by Herndon police officers while Casco was arrested a short time later after an armed carjacking in the 1000 block of Elden Street. "A handgun was recovered during the initial investigation."
