Migrant Gods of Mumbai: Kshetra Maranakatte.
Stumbled upon a very interesting mythological story thanks to this small image that says Kshetra Maranakatte. The deity is the Asura called Kamhasura who was killed by Mookambika of Kollur, a very popular temple that is nearby. Kollur is popular with devotees from Kerala whereas this would probably be the local one that is also worshipped. More details here.
