HUNTSVILLE, Ala.- U.S. Immigration and Homeland Security Investigations are urgently seeking the public's help in locating a convicted Alabama sex offender, wanted on a federal arrest warrant issued in June, for receipt of child pornography in the Northern District of Alabama. 

Matthew C. Harbin, 28, of Arab, Alabama, is a convicted felon who pleaded guilty in 2009 to state charges of transmitting obscene material to a minor.

Special agents have reason to believe Harbin may be hiding somewhere in northern or southern Alabama, or Florida, in an attempt to elude law enforcement. HSI also believes Harbin may pose a threat to others and/or may attempt to flee the country to avoid capture.

Harbin is 6 feet,2 inches tall, weighs 200 pounds and has brown hair and brown eyes.

Anyone with information about this person is asked to contact the agency immediately by calling the 24-hour HSI Tip line at 1-866-DHS-2ICE. The public can also submit an online tip at or by downloading the Operation Predator smartphone app and submitting a tip via the app.

All tips will remain anonymous. Individuals should not attempt to apprehend the suspect personally.
