The statement was made under caution??
First things first, don't say anymore until you are with a solicitor. Most defendants are interviewed under caution. If they decide to give a statement instead this is usually read out in interview. Was this the case??
Also, when answering yuour bail, you should really have access to the CCTV. It is not a God given right that the police should let you see it. Nut any questions resulting from the cops viewing it, should be answered with NO COMMENT. And because you have not seen the tape, no inference can be drawn from a no comment.
Or further stick to your guns and say I CAN NOT RECALL (which reading above, is the truth.
However, if you are allowed to view the tape and your guilt is obvious, ask the solicitor to ask the police if you are cautionable. This is technically bad practice for the police to say yes to such a request but I can assure you EVERY police officer will do this.
What is strictly not allowed is the police saying "Admit this, and you get a caution" But again, this does often happen.
So my advice, don't say a sausage until YOU (and your solicitor) have ALL the evidence. When you get it, either go for a caution and admit everything, or go with the flow.
