stolen 2016 Ghost Tacana5

The bike was placed in my backyard behind the stairwell up to the deck. I usually lock up there but was dropping something off at home for about 5-10 mins. I saw the thief take my bike from it's place through the window I have in my kitchen which is in direct view of the bike. I ran out to chase the thief down but didn't have my phone on me to take a video. The thief was with another individual on a black bike with a lime-green stripe on it, he was wearing darker clothes. The thief who stole my bike was wearing green(grey maybe) pants with a dark grey belt. He had a lighter grey shirt on, the shirt had some kind of claw decal on the back of it, like from a high school sports team. The one on my bike looked directly at me and smiled as I chased him down, he had shorter hair, like a buzz cut that had grown out, I could probably identify him. The two road the bikes heading south down 108th Street and then turned east on 67th Avenue.
