Bangalore Metro Rail Corporation — not allowing us to carry eggs in bag

Address:

Bangalore, Karnataka, 560015

I am a regular traveller in metro. Today 3rd august 2019, evening at around 8.20pm i was travelling from rajajinagar metro station to jalahalli cross.in the routine security checking at rajajinagar metro station they refused to allow me inside as i was carrying around three eggs in my bag which was neatly and securely packed. They said it is not permitted.
I demanded list of prohibited items which they showed but no where it was mentioned that eggs should not be carried.

No where it was written nor was informed to us earlier. When we raised objection on this matter, the security staff was very arrogant and asked me out move out of the of the station. They did not have the courtesy to talk in the polite way.
Please clarify is it justified?.
Please take necessary action against security staff available at that point.
