HOUSTON -

An investigation by federal and state law enforcement agencies led to the arrest of a 16-year-old boy on child sexual and trafficking charges.

The investigation began in 2012 when the National Center of Missing and Exploited Children forwarded a cyber tip to the US Department of Homeland Security Investigations Unit concerning the interstate transmission of child pornography.

Investigators tracked the material to a home in Harris County.

When the Homeland Security Investigations Unit became aware of a second transmission from that same location in April of 2013, federal agents and officers with the Harris County. Precinct 4 Constable's Office High Tech Crimes Unit issued a search warrant.

Investigators recovered approximately 4,000 images and video from the juvenile's electronic devices located in the home.

Investigators were able to confirm that some of the child pornography showed the suspect's six-year-old male cousin who lives in Montgomery County.

The 16 year old faces charges of Aggravated Sexual Assault of a Child, Trafficking of a Person, Sexual Performance by a Child, Possession and Promotion of Child Pornography, Indecency With A Child, Exploitation of a Child, and Unlawful Restraint on Monday.
