He was granted bail in 2017 and had been staying at his residence in Sangli.He was rushed to a hospital where doctors declared him dead on arrival early on Tuesday, a police official said without giving more details.Prima facie, Gaikwad died due to cardiac arrest, but the police were waiting for the postmortem report to ascertain the exact cause of death, he said.  There was nothing suspicious, the official added.Pansare was shot at on February 16, 2015, in Maharashtra’s Kolhapur and succumbed to his injuries a few days later on February 20.
