iPhone 6, Stolen from The Workman's Club, Saturday July 18th

My iPhone 6 was robbed from my bag in the smoking room area of the of The Workman's last saturday night after Longitude. It was the 16GB Space Grey model in a very distinctive large Otterbox case that was green and purple. I've tracked the phone to an estate in Blanchardstown but the Gardai say Find My iPhone app isn't accurate enough to go knocking on doors. I would appreciate ANY help at all — I think I know the guy who took it and could identify him again. I'm willing to buy it back. The phone is in Lost mode, blocked, blacklisted etc and useless to the thief unless for parts.
