Both NCP and Congress activists alleged that bogus voting had taken place during the polls.
Navi Mumbai Police said that at least 15 persons had been arrested for rioting after the clash in the Sanpada area.
On Saturday, Apr 10, the NCP expressed confidence about winning the municipal corporation polls.
The Navi Mumbai municipal corporation is the third largest civic body in the Mumbai Metropolitan Region.
Apart from the NCP, the Congress, its ally in the state and the Centre, is also contesting the polls. The BJP-Shiv Sena alliance is also trying to acquire some seats in the civic body.
The authorities have directed that all wine shops, country liquor shops and permits rooms in the city jurisdiction down their shutters till the voting process is completed.
The step as Section 135C of the Representation of People's Act, 1951, which provides that no spirituous, fermented or intoxicating liquors or other substances of a like nature is sold during elections.
This is being done to avoid a law and order problem in the city.
