Can statements, documents and images provided to assist an ongoing AAIB investigation be withdrawn?

[Micromouse]

can things be unseen? and I'd be more suspicious as to the reasoning why they have been withdrawn, and be looking deeper

Probably not - but that is something you'd need to discuss with a lawyer:

"The powers of an Inspector
Inspectors have powers to take signed statements
from anyone involved directly or indirectly with the
accident. They can remove and retain all relevant
books, papers, documents or articles and can
have access to and inspect any place, building or
aircraft for the purposes of completing their
enquiries.

And from: https://www.legislation.gov.uk/uksi/201 ... on/12/made

Additional provisions – Inspectors’ powers
12.—(1) The power conferred by subparagraph (f) (power to call and examine witnesses) of paragraph 2 of Article 11 of Regulation 996/2010 must be exercised by the service of a summons signed by an Investigating Inspector and requiring any person (“witness”) to attend a witness interview at a time and place stated in the summons, in order to—

(a)answer any question, or
(b)produce any document, record, information or other evidence,
which is, in the opinion of that Inspector, relevant to the safety investigation.

So if an inspector decides that what you have given might be relevant, even if you withdraw it, they could immediately get a summons for you to reproduce it.

If they aren't relevant - you could just ask them.
