Any phone call involving winning a prize, spending a bank card or committing a crime is made by a liar, and the public security law does not handle cases by phone. Tell you what he is calling, tell you the alarm number, location, etc. You can't confirm the authenticity. Don't worry about his request, just remember to operate the bank card. No transfer, no contact, nothing. How to criminally detain or arrest a civil act? Liars don't know the law. Ignore him.
If you want to find someone, you can call 1 10 and ask directly.
