"Thackeray is working as terrorists by giving such an statement...it will help divisive forces," a party spokesman said here.
"While terrorists are using serial blasts to damage unity and integrity of the country, Thackeray's irresponsible statement are doing the same thing," he said.
Maharashtra Navnirman Sena (MNS) chief Raj Thackeray today blamed "hordes of migrants" coming to Mumbai for the spurt in crime rate in the state.
He said that Thackeray should know that people of Uttar Pradesh and Bihar had contributed towards development of Mumbai and the products manufactured in Maharashtra were used all over the country giving the state prosperity.
It was fundamental right of every citizen to earn livelihood wherever he wanted in the country, he said adding that, there was no separate constitution for Mumbai or Maharashtra.
