Scam/Fraud

British guy pretending to be part of the Police Cyber Security department, saying my details have been found at a ladies house along with all my login details etc, he then started to asking about crypto and hardware wallets. He then gave me a crime reference number which he wanted me to confirm back, no doubt to record me saying them, I hung up and blocked the number and reported to https://www.reportfraud.police.uk/reporting-a-fraud/ Please be aware!
