Four people have been arrested in connection with a string of tennis shoe robberies in Gwinnett County.

Rashawn Jones, 20,  Tyrese Watkins, 17, and unnamed 16 and 15-year-old juveniles were arrested recently on charges of robbery by sudden snatching, according to a news release from the Gwinnett County Police Department. Brown, Watkins and the juvenile also face armed robbery charges.

Gwinnett police said four robberies occurred in the Sweetwater Road/Club Drive area over the course of a month. The scheme involved people looking to sell tennis shoes on Facebook, and prospective buyers, who offered to pay more than the seller asked.

In each of the four cases, the seller would show up with the shoes and the suspect would snatch the shoes and run, police said. One victim chased the shoe thieves on foot, but was confronted by one of the suspects with a handgun. Another victim was robbed at gunpoint, authorities said.

Watkins and Jones were arrested and taken to the Gwinnett County Detention Center. Brown and the unnamed juveniles were being detained in the Gwinnett Regional Youth Detention Center.
