A Winnipeg man has been charged with child luring after allegedly offering money for sex to a police officer posing as a teen girl online.

Officers began tracking a man on July 20, after he allegedly posted an ad on a popular social media website looking "to meet 'YOUNG' women for sexual encounters," police said.

Posing as a 15-year-old girl online, an undercover officer responded to the ad and the two started text messaging, police said.

The man then arranged to meet with the teen with the expectation of offering money in exchange for sex, police said.

He was arrested Thursday and charged with two offences, luring a person under the age of 16 and obtaining sexual services from a person under the age of 18.

He remains in custody.

Anyone who comes across child exploitation can file a report at Cybertip.ca, police said.
