Mumbai Traffic Police — Inappropriate behaviour

I was travelling from Jogeshwari to goregaon east this evening. And I always take a right turn to take the new Jogeshwari flyover till the highway. While on the turn there was a traffic police named Ankush Rawle who stopped me saying there was a no right turn board below the signal ( which cleary wasn't visible to a naked eye). His tone towards me was very aggressive and unprofessional. He kept pointing his fingers towards me and kept raising his voice.
