Tiwari, who returned to Mumbai on Sunday evening, said, "I was sleeping in the pandal when I was woken up by a policeman's boots that stamped on me."
"I was driven out by the police with lathis. I must've ran at least 3-4 km to save my life," said Tiwari, who is in Mumbai now.
"Although my injuries are not noticeable enough, my body is aching because of the lathis I got from the police," he added.
Baba Ramdev's beleaguered anti-graft hunger strike ended early Sunday amid violence, as a heavy contingent of police stormed the protest site with teargas shells and charging batons, while the yoga guru himself was evicted out of Delhi.
Tiwari was the only celebrity from the glamour world to join Ramdev at Ramlila Maidan.
