Star Bazaar — staff behaviour

This is to report an extremely offensive behaviour i experienced at the star bazaar, thane korum mall outlet.
I was shopping and completed billing, but just when i was exiting the store, to my surprise, the sensors beeped owing to an un-billed item in my trolley. I was taken aside & despite claiming that the staff at billing must have missed out on billing the same, they only accused me. The supervisor and security staff started yelling and me and searched my bag. A lady took me inside and searched me thoroughly, in a very inappropriate manner. Ofcourse they found nothing as my intentions were always bonafide. I was extremely harassed, for no fault of mine whatsoever.
After all this, i was fed-up and wanted to leave instantly, but i was forced to go back and bill the same, else i wouldn't be permitted to leave the store. I was threatened that they would call the police and that i should never return to shop over there.

This is truly unacceptable, unprofessional and insulting behaviour on the part of security and the supervisor. I was a loyal customer since many years, but after seeing that their intentions are only to harass innocent customers, i have turned completely against entering any star bazaar store henceforth. I will also ensure i am heard by many, to prevent this from happening with anyone else.
