Can the bank file a case for bounced cheque after six years?

Hi!

I have a bounced cheque in 2016 however, the bank has not filed a case against me. I am not sure why though, as I have checked with the police station and they said that my record is clear.

Recently, I have been receiving calls from a debt collection agent and he is threatening me that a case will be filed immediately if I don’t agree to settle.

My question is, can they still file the case even though it has been 6 years since my cheque has bounced?

Hope someone can answer, please.

Thank you.
