Never mind, thanks.
You need to get a solicitor instructed (frankly you would have been wise to instruct a solicitor BEFORE attending the police station).
If you private message me I may be able to recommend one reasonably local to you.
1. Did you follow the earlier advice to get a solicitor? It seems that may be the only good advice you got from your accountants although there are usually two sides to every story.
2. Having a police interview without a soliciotr was unwise. The police will have already made up their mind and anything you say will be used to dig a deeper hole.
3. Hope that David Winch sees this post and provides his usual impeccable advice.
Edit: David beat me to it!!
"I was in essence a NEGLIGENT director"
Fixed that for you.
Seems that you spent longer writing that post than you did fulfilling your legal obligations as a director. You need legal advice.
