Two Fulton County men were arrested in connection with the armed robbery of a liquor store in south Forsyth after they caught the attention of neighboring merchants, authorities said.

Jamario Stephan Barnwell and Jonathan Blake Reid, both 21, are being held without bond at the Forsyth County Detention Center, jail records show.

They were arrested Friday night and charged with two counts each of armed robbery.

In addition, Reid faces two counts of aggravated assault and one count each of possession of a firearm during the commission of a crime and tampering with evidence.

Johns Creek Police Lt. Chris Byers said the men also face armed robbery charges in connection with an incident at a package store in that nearby city.

In Friday’s incident, Forsyth County Sheriff’s Maj. Dan Jagoe said deputies were called to Sharon Crossing Beverage, 1465 Peachtree Parkway, about 9:20 p.m.

He said one of the suspects had reportedly entered the store wearing a mask, brandished a handgun and demanded money. After robbing the store and two employees, the man fled.

The search for the men was aided by two business owners in the shopping center.

Jagoe said the merchants had noticed two men earlier that night in a 2009 Toyota Corolla behind the shopping center.

They wrote down the license plate number after they later saw one of the men get out of the vehicle, which had moved to the front of the center, and enter the liquor store.

"That really helped us out a lot," Jagoe said. "It was great they were so observant."

Authorities traced the car to a Johns Creek residence, where Johns Creek police then found and arrested the suspects.

Jagoe and Sheriff’s Lt. Col. Gene Moss said the arrest was the result of a "good collaborative effort" between the two agencies.
