Okay, the charge was fraud. That is all I'm going to say. I've now decided that even if the police come across this thread I don't think it will matter.
So in summary:
- I was told it was fraud but nothing more.
- Evidence was only found at ONE of my colleagues addresses
- I had nothing to do with it and this is backed up my a lack of evidence
- The rest of us were arrested probably because we are good friends and seen together around the building (lunch, coffee breaks and occasionally work

)
- The officers were actually friendly and polite, probably because I am the same way. My only gripe is the lack of information and cleanliness of the cell.
While I was lying in the cell I wasn't really worried because I knew that I've done nothing wrong even though I was going a bit crazy trying to think of what it could possibly be. I was pretty relaxed when I went to the interview probably because I was so tired and my solicitor had told me that no evidence had been found.
The arrest itself is not my real complaint. One day at the police station is nothing really. It's the fact that my computers and phone have gone and I'm suspended from work while they investigate and all this is based on is one person incorrectly pointing the finger at me.
