Green Day Star Helps Couple Retrieve Stolen Pitbull

Green Day rocker Billie Joe Armstrong has helped track down a couple's stolen dog with the help of his Instagram.com followers.

The American Idiot star urged his 436,000 followers to help David Baker and Cassandra Niki locate their pet Mochi after learning of a campaign to get the mutt back after an apartment break-in in San Francisco, California over the weekend (10-11Jan15).

Armstrong's post on Monday (12Jan15) did the trick and a day later the pitbull was found safe and well and returned to her owners.

Armstrong posted a note confirming the news on Tuesday (13Jan15), writing, "Just want to let everyone know that Mochi made it home."

He also posted a photo of the happy dog on Instagram.
