7:27am to 7:31am
Vijayanagar Metro Station Entry Platform A
To share the standard procedure to be followed by newspaper agency guy.

Morning as i tapped the metro card and entered the VIjayanagar Metro station.
There was newspaper being placed by the agency guy or metro guy.
I grabbed one newspaper from the stand and that guy stopped me from picking the newspaper and mentioned to stop till he takes the photograph, i picked and started to leave, he told to keep it back in a rude way, so angrily i threw the paper on the same stand and that guy started to abuse me with bad language and scolding me as illiterate and harass me badly like a rowdy, and he grabbed my shirt collar and pulled me during which my neck gold chain broke and i lost my gods gold pendent around 8gms at the metro station, which i realized about my broke chain later stage only.
Then i left back to pick my train.
I would like to understand:-

1) What is the process to be followed by the newspaper agency or placing person?
2) If there is standard process then why is it not displayed why public is allowed to pick freely?
3) Would like to get this process either by RTI act by writing to PIO by paying the relevant fees.
4) Where to find the authorization provided by BMRCL/Govt to place the free newspaper(Around 10numbers only)?
5) How many number of newspaper should the newspaper person should place inside?
6) How many can he handover to metro personnel?
