How do you handle when someone tries to instill guilt in you?

From a perspective to hindrances to meditation this may fall under remorse and regrets, but not very apt in that sense. Using Buddhist philosophy to get over and respond, how do you handle when someone tries to instil guilt in you, like trying to make you feel like you have done something wrong, you are a bad person, I am a victim, you are a perpetrator. How to respond to such a person? Sutta references are appreciated but otherwise, any workable answer adhering to keeping Buddhist precepts and practise is welcome.
