A Monmouth County man who authorities said failed to register as a sex offender was arrested in Barnegat Township June 20 by State Police after they received tips on his location from social media.

Two days earlier, troopers asked for the public’s help finding Marvin Sanders, 37, of Shrewsbury Township, who failed to register under Megan’s Law, according to a post on the State Police’s Facebook page. The public’s “likes and shares” helped them find him at a home in Barnegat.
