South 24 Parganas additional superintendent of police Abhijit Sinha today said the arrests were made last night following complaints by some women who had visited the park during the day and used the changing room.
The CCTV camera in the changing room and several others from various areas of the park were also seized, he said.
Manshu Tandon, CEO of Aquatica, told PTI that police were investigating the case. "But we want to say that there has been no breach of privacy as was claimed because the CCTVs were not there in the ladies' changing room."
The CCTV had been installed in the men's locker room and it continued to be in operation in the converted women's locker room as the staff had forgotten to switch it off.
"The CCTV ran for about one and half hours. After it came into light we switched it off immediately," Tandon said.
The incident took place just weeks after Union HRD Minister Smriti Irani spotted a hidden CCTV camera in a changing room of a Fabindia outlet in Goa.
