Will it affect my career,bgc or any other future verification?

I had gone to a supermarket 2 weeks back I had some things bought few days earlier from the same store in my bag At the exit they told “it is not allowed ...show the bill ..” I didn’t have it as I had thrown it long back. Moreover my bag’s zipper was damaged and coming undone , I had to zip it constantly and I was taking things similar to what I already bought , so even if cctv was taken no one will care to believe me but I digress. They started making a huge fuss and I got terrified, I didn’t know the local language also. I didn't have anything to prove I bought it . The manager asked me to write a letter that I tried to take it... I wrote because I thought he will let me go (my stupidity), but then he called the police Police officer came ...he gave the copy of letter , my driving licence copy Officer took me outside asked me for my office id and he took a pic in his phone He told he will get a warrant and then release me or something like that. Then on the way to station he asked me if I have any money...I just had some 10 rupee notes He asked to get 2 coffee... He told he will file petty case..I started losing my mind...I cried a bit After some time he said “warning ...do not repeat” Then let me go He still has that letter,DL copy and my office id pic. I'm worried if there will be any problems with that.If they will file any case without my knowledge. I have checked the online portal for FIR,arrested persons, but nothing in there in my name. I’m working in a IT company since 3 years, Will there be any record/petty case/complaint against me? Will it affect my career, BGC or any other future verification? Please guide me. Thank you
