Supporters of the Shiv Sena corporator from Santacruz, Mohan Lokegaonkar, violated silence norms while they celebrated near the Brihanmumbai Municipal Corporation (BMC) headquarters after he was elected chairman of the works committee (suburbs) on Tuesday.
Lokegaonkar who garnered 18 votes defeated Congress's Rafiq Sheikh who got 10 votes.
Over 200 supporters burst crackers and danced, without taking official permission.
"We did not take any permissions. Even Lokegaonkar had no knowledge of the celebrations. We just wanted to express our happiness after his win," said Suhas Naik, one of the supporters.
The police confiscated their musical instruments, which were returned after the supporters paid a fine. "We charged them a fine of Rs5,000," said Pradeep Londe, police inspector, Azad Maidan Police Station.
Mayor Shraddha Jadhav justified the act and said, "Such celebrations are acceptable once in a while. People should understand this and participate in the happiness of others."
When asked about the violation of rules, she said, "There are many other places where rules are being violated. Let us concentrate there."
Lokegaonkar, however, said his supporters will face legal consequences for their act.
"If they have violated any rules they will face legal action, even if they are my supporters," said Lokegaonkar.
