Police are searching for a 24-year-old man wanted in connection with an online child-luring investigation.

According to police, the man communicated with two young girls through social media.

"During the communication, he made demands for nude photographs of the girls," police said in a statement Monday.

Police said the man, whose online name was "Brandon G. Davidson," threatened to expose the girls on social media if they didn't send additional nude images or "comply with his sexual demands."

Brandon Walker, of Richmond Hill, is wanted on a number of charges including: two counts of luring a child under the age of 16 years; two counts of making child pornography; and two counts of extortion.

Police believe there may more victims.

Anyone with information is asked to contact police at 416-808-8500, or Crime Stoppers at 416-222-TIPS (8477).
