I bank with and hold credit and debit cards issued by NatWest. I'm not a customer of any other bank. Equifax CreditExpert recently alerted me to an unexpected search on my credit report. The company which initiated the search was "Royal Bank of Scotland - emc Compu" and the ostensible reason "Identity Check to comply with Anti Money laundering regulations".
I've 'phoned Equifax, RBS and NatWest to seek an explanation. To paraphrase, their respective answers were "It won't affect your credit rating", "We can't help unless you have evidence of actual fraud" and "I don't think it was us".
Obviously I'm concerned about identity theft. Google reveals that a few other people have experienced similar unexplained alerts but I've found no reports of malign consequences, suggesting that the alerts may be obscure but harmless artefacts. I'd be grateful if anyone can throw any light on the phenomenon or offer an opinion on whether it would be worth investigating further and, if so, suggest other approaches?
