Tamil Nadu State Transport Corporation [TNSTC] — regarding the inconveniences by the transport department

I am d. Venkata sai vivek from andhra pradesh. I stay in semmancheri area. Sir i brought my bike from andhra pradesh i am a student of sathyabama university and stay at dlf garden city. Befor bring my bike to chennai i have enquired at sholinganallur rto office regarding the noc or the procedure for bring my bike. Some of the traffic police are asking for noc form. So we just went and asked them regarding noc, so they told us when u bring your bike here you need to change your registration. As i am a final year student i will be staying in chennai for one more year. So i asked them for short term road tax which se if the police me at madipakkam area have suggested us. Ao we went and asked them for short term road tax it is a strange thing that the person in the enquiry booth have told us there is no short tearm road tax and he also told us no need of noc as now a days so many vehicles from other states are traveling in chennai so there is a new rule that noc is not required. As the person in the rto office told us we have not bought noc certificate. But today near dlf garden city police men have stopped us and asked us for noc. We told them the same what the rto authority person have told us but still they are asking for noc. We again repeatedly saying the same thing. This police men have been saying we don't know any rule such like that. So they asked us to pay a fine of rupees 1500, or he will seizey vehicle (Bike), finally we paid 500 rupees and when we asked for the receipt there is no response from them and they started to pay again to pay 1500 fine. My main problem regarding this issue is heresome police men says noc is required and some police men says noc is not required and the rto says no need of noc. But some police men. Says we need noc or we will not let you go. Regarding this every people should get an idea and authority should not miss lead or miss guide the people as a first step i am experiencing my pain through this if this doesn't work we are ready to meet the respected transport minster regarding this issue to get a better idea and how the police department is miss using their powers
