Investigators have charged a 24-year-old Dawsonville man with armed robbery weeks after they say he robbed a woman he met on an online dating site.

Gavin Edward Lee was a suspect early in the investigation, according to Dawson County Sheriff's spokesman Capt. Tony Wooten.

"He was charged once we were able to develop enough probable cause to obtain a warrant," he said. "He denied his involvement in the early part of the investigation, which led to the false statement charge."

Lee is also charged with theft by taking, simple assault and giving false statements, jail records show.

Authorities said Lee and the woman were in a parking lot of the Gold Creek subdivision during the early morning hours of May 26 when he brandished a pistol, took her purse and made her exit the car.

"He took cash and her cellphone that was valued at about $500," Wooten said.

The woman, who has not been identified, was not injured in the incident.

Lee is being held without bond, according to jail records.

Just days after the May 26 robbery, sheriff's investigators arrested a local couple for luring a man to a Dawsonville home under the pretense that he was there for a date with the woman.

The man, who had reportedly met the woman on the Internet, was allegedly ambushed when he arrived at her home.

While the cases are unrelated, authorities urge caution when agreeing to meet someone from the Internet.
