I had a phone call the other day from someone identifying as police officer saying they raided a house and found something likely belonging to me and there is ongoing investigation. They knew my basic personal details. What was interesting that there was almost no gap between what I said and their response and voice sounded quite natural. I kept it for a while, because once I had a doctor call me who sounded like AI, but it was actually his real voice and it was embarrassing as I called him out for being AI. Anyway, they tried to get me to fill a police form (they knew my email as well) - this is where I realised this is a 100% scam. The email was spoofed. I reported this to the police, but they were not interested. I thought impersonation of police officer would be a serious matter. Apparently not in the UK.
