He had been elected as the party's city unit president in mid-2013.
Patankar had been allegedly attacked by an angry mob of Shiv Sena and BJP activists on December 23 last year after the defeat of Sena nominee Pappu Kadam in the elections to the Civic Transport Committee chairman.
Patankar was accused of engineering a split in BJP, due to which Kadam was defeated by one vote in the polls. Patankar later resigned from the post and reportedly went missing.
