Dear metro authority of bangalore
Subject - harassment by security guard for carrying food item
Date of incident - 7th may 2019
Place of incident - trinity metro station
Person accused - security guard & station manager

Here i am reporting unacceptable practice & harrasment by security lady everyday at trinity metro station. I would request investigation & termination of the employee.
On 7th may at trinity metro i was stopped by the security guard & detained & questioned for 20 mins for carrying a tetra pack of amul buttermilk & asked to throw the pack before i enter the station, which as per the attached rule book is not mentioned neither anywhere mentioned a passenger cannot carry normal food items, when i mentioned bout the rule to station manager he could not validate nor stopped the lady from harrasing me further.in entire country in none of the metro i have faced such issue or security guards who harrash passengers like bangalore trinity metro does without any valid reason. The cctv footage can be checked on the incident.
The same security guard has harrased me once before along with her colleague. Even after reporting there has been no action taken by trinity metro station manager.
I seek justice & seek metro trinity to be fined for harrasment to passenger.
