The Shiv Sena workers on Monday smeared ink on the Observer Research Foundation (ORF) Chairman Sudheendra Kulkarni, who is organising former Pakistan foreign minister Khurshid Mahmud Kasuri's book launch here.
"As soon as I stepped out of my house and got into my car, around 8-10 Shiv Sena workers attacked me and threw ink on my face," Kulkarni told ANI.
The attack comes in the wake of Kulkarni's refusal to back down from organising Kasuri's book launch.
"I profusely thank MaharashtraCM @Dev_Fadnavis for his principled & firm stand against #ShivSena threat to disurpt #Kasuri booklaunch. #Mumbai supports India-#Pakistan dialogue for peace," Kulkarni had tweeted earlier.
The Shiv Sena has been vehemently protesting against Kasuri's book launch, saying it was an insult to the Indian soldiers who had died in the recent ceasefire violations by Pakistan, and had warned that there would be repercussions if the event was not cancelled.
