After blackening the face of Observer Research Foundation's Sudheendra Kulkarni on Monday for organising the launch of a book by former Pakistan foreign minister Khurshid Mahmud Kasuri, Shiv Sena has now reportedly threatened Congress supporter Tehseen Poonawalla over a Pakistani food festival.

Shiv Sena came under sharp criticism on Monday from all quarters after its party workers threw ink over the moderate BJP leader, Kulkarni, hours before he was to host Kasuri in Mumbai. 

The right-wing party headed by Uddhav Thackeray has now allegedly threatened Poonawalla for planning a Pakistan food festival in Pune, Maharashtra. 

"The Shiv Sena are thugs. Even threatening me on Facebook for a Pak Food Festival I am organising," Poonawalla tweeted. 

According to reports, the threat came from the brother of Shiv Sena's Pune president Ajay Bhosale. 

Poonawalla said he will be filing a complaint with the Pune police over the threat. 

"Who the hell is the Shiv Sena? And why must #Pune‬ fear the Shiv Sena. I'm raising my voice and in a concrete way. On the 7th of November I'm hosting a Pakistan Food festival in my Pune. Chefs from ‪#Pakistan‬ will be cooking and I'm trying to get in touch with ‪#GhulamAli‬ ji's son. I would love it if GhulamAli sahab performs in my Pune on 7th Nov. I am going to stand up to these bullies the Shiv Sena," Poonawall wrote on his Facebook page. 

Earlier this month, Shiv Sena had protested a planned concert in Mumbai by Pakistani ghazal singer Ghulam Ali. The concert was finally called off, though the singer later accepted Delhi Chief Minister Arvind Kejriwal's invite to perform in the national capital.
