Shiv Sena on Tuesday slammed the Uttar Pradesh government over the death of Mahant Narendra Giri, and claimed that "Hindutva was strangulated in UP". "This case should also be probed by CBI. The mysterious death should be probed independently," Sena leader Sanjay Raut said. According to the UP Police, Mahant Giri died by suicide and a note was also found.
