OKC Police Arrest Cop Impersonator For Child Sex Crimes

A metro man accused of impersonating a police officer was arrested today on new charges. He was booked this afternoon and court documents show he's now accused of child sex crimes.

Oklahoma City police said 31-year-old David Roberts preyed on a 15-year-old boy and took the kid out of state to have sex with him.

Investigators said Roberts picked up the boy from his Mustang home on Christmas Eve.

New court documents said Roberts met the boy "through the internet on a homosexual social site and they arranged to meet to exchange drugs."

Police said Roberts took the boy back to his place "where Roberts injected the juvenile with Methamphetamine."

Police believe Roberts took the teen to Joplin, Miss. where he "continued to provide/inject the juvenile with meth" and convinced the boy to have sex.

The search warrants said "Roberts videotaped the sexual act."

We reported on Roberts last month after a metro driver called 911 and said he was impersonating a cop.

Officers arrested him then for impersonation, and now he's back behind bars.

Police said the 15-year-old victim managed to get away from Roberts after 10 days with him.

David Roberts is in the Oklahoma County Jail tonight on a $500,000 bond.
