The regulator said it has been undertaking several campaigns to educate the investors to be vigilant while taking investment decisions based on stock tips. "There are several million Russians who can lift their head up from propaganda and try to look for other sources, and I'd say that most look for it on Telegram," he said.

Sebi said data, emails and other documents are being retrieved from the seized devices and detailed investigation is in progress.
