About $15,000 worth of audio and video equipment that was stolen from a charity event has been returned anonymously.

As News 12 first reported on Monday, Dan Marquardt was filming "Dee Snider's Ride for Melissa's Wish" -- a charity motorcycle run on Sunday afternoon -- when someone swiped his gear. But on Monday night, Marquardt says he received a Facebook message from someone he never met before.

"He said he saw a bag sitting outside the Friendly's on Montauk Highway in Mastic Beach," Marquardt says. "He saw somebody put it there, he looked into the bag, saw there was equipment in the bag."

It turns out his gear was stuffed inside of a Christmas bag. Marquardt says someone at Friendly's notified police, who took the equipment into their possession. Police confirmed it belonged to Marquardt by spotting a passport that belong to a friend of his who died a few years ago.

Marquardt says all the equipment was there. Now he says he'll happily return to his normal spot behind the camera, now that he has his once again.

Marquardt says he'll keep the Christmas bag attached to his gear.
