Editor of IBN-Lokmat Nikhil Wagle on Friday said the attack on the Marathi news channel may have been instigated by Shiv Sena MP Sanjay Raut.
"I suspect Raut is behind the attack," Wagle said.
"Bal Thackeray has become old. Uddhav Thackeray has lost control over Sena and elements like Raut are flourishing in that party," he said.
Raut, who is also editor of Sena mouthpiece `Saamana', said earlier in the day that the attack was "spontaneous".
"The (channel) office is located in the constituency from where Raut's brother contested as a Sena candidate," Wagle said. "I have been facing Sena attacks since 1991 and it is difficult to believe that any attack takes place without orders from Sena leaders," he said.
"Sena has insulted Marathi by attacking a Marathi channel," the veteran journalist said.
