New Delhi: The Delhi government on Friday cracked down on 77 hotels for violating pollution norms in the national capital, sending closure notice to all of them.

"The Delhi Pollution Control Committee found that 77 hotels were operating without license from municipal corporation and Delhi Police and Delhi Pollution Control Committee. They did not have pollution checking devices either," Delhi's Environment Minister Asim Ahmed Khan said.

The hotels were located in south Delhi's Mahipalpur area near Indira Gandhi International Airport.

"The government issued a closure notice to them," the minister said, adding that 27 hotels were sealed.

Khan said the government has also directed the authorities to cut water and electricity connections of the 77 hotels.

The crackdown came after a direction from the National Green Tribunal.
