The activist Mallikarjun Bhaikatti had, through an RTI query, revealed that around 14,000 square feet illegal construction was carried out in a four-storeyed building and boys hostel on the Latur-Nanded road.

Bhaikatti had addressed a press conference at Latur yesterday to “expose” the illegal construction, police said.

The Sena workers brought Bhaikatti to the college premises today when around 4,000 students were present and assaulted him with an iron rod, before blackening his face.

The injured RTI activist has been admitted to a hospital in Latur.

Local Sena activist Abhay Salunke said Bhaikatti was a “blackmailer.”

Facing flak from various quarters, Shiv Sena sacked party workers who blackened the face of a Right to Information (RTI) activist in Latur Yuva Sena chief Aaditya Thackeray said on Saturday.

“Heard of the unfortunate incident in Latur. The party strongly condemns the disgraceful act. Those involved have been removed from the party,” Aaditya, son of Shiv Sena president Uddhav Thackeray, tweeted.

Meanwhile, Latur police have detained 26 persons in connection with the incident.

Earlier this month, Sena workers had blackened the face of Sudheendra Kulkarni, chairman of the Observer Research Foundation, in an ink attack ahead of the launch of Neither a Hawk Nor a Dove: An Insider’s Account of Pakistan’s Foreign Relations authored by former Pakistan foreign minister Khurshid Mahmud Kasuri.
