After paying for the items, as I was leaving the store, was stopped on allegation I'd been seen changing price/prices (not specified). Very embarassed, I said things that could be construed as admission. They copied ID info and took my picture. Not asked to sign anything and no police called. Store kept all items, even ones they knew I could not possibly have changed and some in purse I could not prove I had previously bought - they still had store stickers but I no longer had a receipt. They did not return my check. Items were second hand, worth $50 at most. No damage to items.
Received civil action letter from Palmer et al, wanting $343, saying that paying it doesn't affect criminal charge. Can there be a criminal charge if no police/arrest? What charge if I ignore the letter?
