After believing he was giving a woman a ride to work in Roswell, police said a man was robbed at gunpoint in a hotel parking lot.

A Roswell police officer was filing out a report in his patrol car when a man approached him and said he was the victim of an armed robbery, spokesman Sean Thompson told AJC.com.

The victim told the officer he was approached by the woman at a Chevron gas station. He initially declined to give her a ride, but then allowed her to get into his truck.

She first asked to be driven to Taco Bell for work, then directed him to a La Quinta parking lot on Old Holcomb Bridge Road, where another man opened the passenger-side door, Thompson said.

The victim got out of the truck, saying he expected to fight the man, but said the suspect pulled a gun out of his waistband and demanded his wallet, police said. The victim refused, but gave him about $60 to $70 cash.

The suspect then demanded the keys to the truck, according to the victim. He said the man and the woman then drove away together.

The incident is under investigation.
