Ok, another update. Sohail was arrested and taken for interview. Whilst there his house was searched fully. In interview he told the police that he went for a walk and bumped into some people who offered to sell him the phone (for £75). He just happened to have £75 cash on him so he brought it. He's admitted he knew it was probably stolen. So he has received an 'adult caution' for handling stolen goods but there's not enough evidence to go after him for the burglary. There wasn't any other stolen property found at his house.
So he's free.
In much much better news I had the following dropped off not long ago:
It was a bit dirty but otherwise fine. He'd put a lock code on it so I had to use Cerberus again to get on the phone! There wasn't anything on it other than the calls and texts I'd already seen, randomly he'd installed Prey on it too! I've just wiped the phone for piece of mind and cleaned it up with alcohol wipes! Replacement sim card should be with me early next week and I'll be back to normal.
I was chatting with the officer who dropped it off, it was his case. He apologized for the handling of the evidence I had given, apparently it hadn't been passed on properly from the call room and it was only after my repeated calls that it was elevated this afternoon. Regards Sohail it seems to be a case of what can you do. There's no direct evidence that he was at the seen of the crime and they can't disprove his story despite being pretty sure he was involved or as a minimum knows the people involved well.
So a lot of people guessed correctly regards the tap on the wrists! But yay for getting the phone back which is a lot better an outcome then most get from a burglary!
Police response in the end was very good, just some silly people in the call center. But the response from those going to his flat was awesome! So if any of you are reading this massive thank you for going the extra mile and getting in there!!!!
Big thank you to everyone in the thread! Really great to read all the comments (even the conspiracy theorists!), kept me going through the frustration and annoyances! Plus there were a good few tips without which I might not have had the successful outcome!!!!
Also I might not work for Cerberus, but I'm sure I'm going to be a life long customer!!! Top quality software. But in future I'm going to make sure to install it properly with root. I think I was very very lucky that he didn't bother to wipe the phone!
Thanks all!
