"After checking at prominent malls in the city yesterday, though nothing objectionable was found; notices have been served to 45 showrooms to change location of cameras," a senior police official said here.
Of the 45 showrooms served notices, 10 each are in Fun, Saharaganj and Phoenix, 12 in Wave and three in SRS, he said.
They have been asked to change the location of CCTV cameras mostly pointing towards trial room, police added.
He said that such incidents were a blot on the society, which must be checked at all costs.
Union Minister Smriti Irani on Friday raised an alarm after she spotted a hidden camera at an outlet of a leading garment store in Goa that was pointed towards the trial room she used while trying out some clothes that led to a case of voyeurism being filed and arrest of four employees.
