Police said a 19-year-old has been charged in armed robberies at Krystals at 307 Cherokee Blvd. and 1850 Hixson Pike.
Nolandus Dwayne Sims, of 2302 Windsor St., is facing two counts of aggravated robbery. Police said he admitted to taking part in the Hixson Pike robbery, but not the one in North Chattanooga.
Police said a female was with Sims at the Hixson Pike armed robbery and another black male on Cherokee Boulevard. He told police the idea for the Hixson Pike robbery was by a female named Meika Jones and he went along. Police have not been able to locate a Meika Jones.
Sims said he and the female were armed with BB guns.
Police said on Dec. 30 at Hixson Pike the pair went in armed with guns. They stuck a gun to the neck of a female employee and forced her and two other employees to the floor. The female grabbed the manager and forced him to the office. She had him open the safe and empty the deposits.
The pair fled on foot toward the nearby Dollar General Store.
Police said on the Cherokee Boulevard holdup on Dec. 13, the pair forced employees to the floor. They then made the manager open the safe.
One robber told the manager, "This is a robbery, not a murder."
The pair left in a gold Nissan Altima.
Police said the same pair of shoes was worn in both robberies and the holdups were similar. Officers said Sims was wearing the same pair of shoes seen in videos of the robberies when he was questioned last Friday.
