Sub - let the shop without agreement

You can get back the possession on specific grounds as provided under the Local law. Why you are seeking repossession?

Bangalore /Karnataka

I need to know what are my rights, i had sub let the shop on verbal  agreement to Mr X  and original owner Mr Y  is now seeking the shop and wants from me  in writing that evrything is resolved and i agree for No objection & return of shop to original owner , land lord says he will use help of goons or politician to evict the current tenant  Mr X 

I have paid all due rent till DEC 2016 , he has given me the receipts , from Jan till April 2017  i have not paid anything as he did not ask as well 

Shop is in Bangalore /Karnataka , multiple reasons : Landlord wants now for his personal reason , actually he is not telling the real reason may be he wants to 

give it to new tenant for higher rent / wants to sell the building to sister .

He wants me to vacate in 2-4 weeks , he is threatening to put locks on shutter , can he do this , he can approach the legal way by giving notice , what are my 

rights in this situation if he put his own locks  ?
