According to Mark Techmeyer of the Jefferson County Sheriff's Department, an 18-year-old went to police and told them he did approach the boy in order to get information on his ex-girlfriend.
The man's ex-girlfriend lived down the street from the boy in the 16000 block of West 2nd Avenue in Golden.
He was hoping the boy would go to the door of his ex-girlfriend to try to get her attention. When the boy tried to walk away, the man got out of the car and started to approach him.
Techmeyer says he was a man making a "really bad choice" at the time.
"He is not a suspect in the Arvada attempted abductions back in September," he said.

Techmeyer says the man turned himself in shortly after 10 p.m. Saturday night. He was interviewed and an investigation went on into the night. He was not released until 5 a.m. Sunday morning.
The 18-year-old may face harassment charges.
He was released after being cleared.
Techmeyer says the boy's mother's actions in taking a picture of the car were a "flash of brilliance" and helped tremendously in getting the suspect to turn himself in.
