He said "those who indulged in the violence need to be unmasked and their faces must be known to the whole country", adding that in due course they are bound to be exposed.
Thackeray said he will not tolerate such attacks in Maharashtra. "I want to assure the youth of Maharashtra that I won’t let anything happen to them & they are completely safe. There will be serious repercussions if anyone tries to repeat what happened last night in the JNU campus in Maharashtra."
The chief minister's remarks came after protests broke out at various cities on Monday including Mumbai against the attack on students of Delhi's Jawaharlal University by a masked mob.

Joining the protest, senior Nationalist Congress Party leader and Housing Minister Jitendra Awhad slammed the ruling BJP-led NDA government at the Centre and said attempts are being made to "destroy democracy in India".
Several political leaders from the ruling Maha Vikas Aghadi have slammed the violence against the JNU students-teachers and demanded stringent action against the perpetrators.
Congress interim President Sonia Gandhi today demanded a judicial enquiry into the major violence. In a statement here, she said the entire party stands in solidarity with the JNU students
"The entire Congress party stands in solidarity with India's youth and students. We strongly deprecate the sponsored violence in JNU yesterday (Sunday) and demand an independent judicial inquiry," Gandhi said.
"The voice of India's youth and students is being muzzled everyday. The horrifying and unprecedented violence unleashed on India's young by goons with active abetment of the ruling Modi government is deplorable and unacceptable", she added.
The Congress President noted that raids on campuses and colleges across the country either by the police or lumpen elements had become a daily occurence, and alleged that this phenomenon has the backing of the BJP government.
"Yesterday's bone chilling attack on students and teachers in JNU, Delhi, is a grim reminder of the extent the government will go to stifle and subjugate every voice of dissent," the statement said.
"Students and youth need affordable education, a deserving job, a promising future and a right to participate in our thriving democracy. Sadly, the Modi government seeks to suffocate and restrain each one of these aspirations." it added.
