The Goa Police Crime Branch is likely to summon top Fabindia officials, including its managing director William Bissell.
Four employees of the fashion boutique chain's outlet in Goa were arrested for allegedly setting up a CCTV camera which overlooked the store's changing room where central minister Smriti Irani was trying out clothes.
"We will be questioning all the top officials," Superintendent of Police (Crime) Kartik Kashyap said late on Friday.
A police official familiar with the investigation of the case said questioning of senior functionaries was necessary to understand the CCTV protocol followed in Fabindia stores and security systems, which were in place at the fashion and fabric company, which has outlets across the country.
The four arrested people have been identified as Karim Lakhani, Prashant Naik, Raju Panche and Paresh Bhagat.
They have been booked under Sections 354 C (voyeurism), 509 (intrusion into privacy) and Section 66E of the Information Technology Act.
