Okay, the dog is probably not a criminal (we'll never know for sure), but he was running through traffic caused enough of a ruckus that the cops temporarily closed the bridge in order to catch the dog. Authorities arrived after someone called 911 to report the pooch.
The dog is in custody (or you know, with animal control) while the police wait for its owners to come forward to claim him. In the meantime, they're calling him Ponch, after Erik Estrada's character on the television show CHiPs.
Look at that lil' guy go! What's he running from?
