He posted the serial number you can give Titus a call and find out. It looks like a Chinese carbon frame to me, it's fishy why would a police force be interested in a carbon hardtail frame. Have you seen their training? They throw their bike in front of the car, that's how they stop my friend's M5(ya m5 getting a reckless ticket by a bicycle cop).
Scam? come on the dude has a feedback of 3 and is already trying to weasel out of inaccuracies in his description by using the "i was told by....." and the classic :"don't bid if you don't feel comfortable" and no refunds = big fat liar, scam artist, thief, grifter, future stock broker/banker.
