"I won't allow them to play here. I have not reneged on my words and won't do so," Thackeray said, in the second part of a marathon interview published in the party mouthpiece "Saamana".
The Sena patriarch also claimed that if he was given charge of the military, he would perform a miracle and set things right in the country within a month.
The Azad Maidan violence on August 11, protest opposing the alleged attacks on Muslims in Myanmar and the riots in Assam, was "pre-planned," Thackeray said.

Shiv Sena and the Raj Thackeray-led Maharashtra Navnirman Sena condemned the Azad Maidan violence, Thackeray said, but "Where were the people who paralysed Parliament," he asked.
Thackeray also warned that he would not "spare" Muslim fundamentalists who fomented trouble in the country.
"I will not allow a single fanatic Pakistani and Bangladeshi Muslim to live in Maharashtra and right up to Jammu and Kashmir where we have branches," the 86-year-old leader said.
