The reason for car detention by police upon a request from the bank

Hi,

Yesterday my car has been detained by the police but I was not aware why. When I have been checked at the police station, they told me that there is an issue with the bank.

What I remember is that some payments were not made since I was stuck in my home country due to COVID-19 from Feb to July 2020 due to which I was not able to pay the monthly instalment.

I resumed work in Aug and started paying my instalments after that. Why did the bank request my car detention?
