What you remember experiencing surely never happened, since it was neither a requirement back then nor at any time since. If you can pull a copy of said police order out of the same hat you keep talking out of there might be something to discuss, but for now it sounds more like defective memory than anything else.
No idea why you were refused an account in 2014, but rules were certainly tightened around middle of the decade. Banks started asking for work permits, long stay visas, copy rental contracts or similar. Bangkok Bank head office in Silom told me that the rules on this became stricter in 2015, and they needed to see either a work permit or a letter of residence from the embassy after that.
