A Flowery Branch man wanted for a May 16 armed robbery turned himself in to the Hall County Jail Tuesday night, police said.

Kajhmon Tybrece Harrison, 19, is suspected in an armed robbery at the Tree Park Apartments in Flowery Branch. The Flowery Branch Police Department put out a lookout for Harrison on Monday on its social media pages.

Investigator Robin Kemp said Harrison “claimed to have a cellphone for sale,” which he allegedly intended to sell to people he knew. The parties involved negotiated a price of $150, Kemp said.

“At the time of the robbery, he set the deal up to meet them over there,” Kemp said. “As they were sitting there waiting on him to come out and bring the phone, he comes up wearing a mask and dark clothes and holds a gun on them and demands their money.”

Kemp said he was unsure of what kind of weapon was allegedly used in the incident.

A Magistrate Court judge signed a warrant this week for Harrison. He remains in the Hall County Jail.
