A Baton Rouge man was arrested Wednesday morning after investigators said he convinced three juvenile girls to send him photos and videos showing them unclothed and then threatened to send those images to their parents and schools if they didn’t send him more.

Matthew Chaney Walker, 24, pretended to be a teenage girl online and somehow persuaded the girls to send him the photographs and videos, according to the arrest report.

He later extorted the three victims — two of whom were younger than 13 — into giving him more naked images by threatening to send the initial images to the victims’ parents and schools, investigators said.

Multiple law enforcement agencies executed a search warrant at Walker’s home Wednesday morning. The investigation was initiated after Louisiana Attorney General’s Cyber Crime Unit investigators received information about the incident from multiple affiliates of the Internet Crimes Against Children task force, which has affiliates across North America, Louisiana Attorney General Buddy Caldwell said in a news release.

Walker, 5126 Claycut Road, was booked into Parish Prison on counts of pornography involving juveniles, extortion, computer-aided solicitation of minors and indecent behavior with juveniles.
