The Kasarvadavali police in Thane have registered a case against the Thane head of the Maharashta Navnirman Sena (MNS) and 15 others for allegedly assaulting an employee and damaging property at Suraj Water Park, a popular weekend getaway in Thane, last month.

According to the police, the incident occurred on the afternoon of November 30, while the FIR was registered on Sunday.

The police said MNS workers created the ruckus over the sacking of some employees of the park.

“A few employees had been downsized by the management on various grounds and the MNS learned about it. On November 30, party workers went to the water park to confront the management. They barged into the park and created a ruckus,” police inspector Nasir Kulkarni, Kasarvadavali police station, said.

He said when the security guard and management tried to stop the party workers from disrupting the daily affairs of the park, they became violent.

“They slapped an elderly manager at the water park and damaged some CCTV cameras before leaving. The manager was waiting for his superior, who was out of town, to return before taking action in the matter. After consultation with his superior, he approached us on Sunday,” Mr. Kulkarni said.

Based on the complaint given by the park manager, the police on Sunday booked Avinash Jadhav, Thane city president of the MNS, and 15 other party activists for unlawful assembly, rioting, damage to property, assault and criminal intimidation under the Indian Penal Code.

The police said they have called Mr. Jadhav for inquiries, and he is expected at the police station by Monday night or Tuesday. The police will also examine CCTV footage at and around the park to identify the other activists involved in the alleged offence, so that they too can be arrested in the next couple of days.
