Police impersonation via video call claiming bank scam involvement

The scammer video call me using Police Uniform and saying my bank account have been using for scamming other people. The fact that my own bank also don't have enough balance. How come it can be used to scam other people 😏 Plus, by SOP and procedure police can't video call and explain through phone. Mins you, everything must be done at Police Station. Tq.
