The incident in Kolhapur on Friday ironically occurred in a state which is the first in the country to pass a legislation against superstition.
As the incident sparked an outrage, Mushrif has apologised for the action of his supporters giving him a 'milk bath' to 'purify' him.
On Thursday, an NCP worker walked to the stage at a public function in Buldhana where Mushrif was seated and poured black ink on him. NCP workers caught the man, identified as Namdeo Dongardive, and handed him over to the police.
The milk was brought in cans and steel tumblers with TV footage showing some of his supporters taking photographs of the minister while he was being drenched in milk.
"I apologise for what my followers have done. I was not aware and did not realise what they are doing. Otherwise, I would have stopped them. I was baffled both the times, when they poured milk on me and when the party worker poured ink on me," Mushrif said.
