Thiruvananthapuram: A 44-year-old electrician has been arrested for allegedly installing a hidden camera in a water heater he had fixed up in his neighbour's bathroom at Muttada near Thiruvananthapuram.
The electrician, identified as Reghunath, installed the miniature camera inside the heater's altometer box to capture images in the bathroom, police said.
The camera had a small radio AV transmitter which sent the images from the bathroom to the computer-linked receiver installed at the electrician's house.
The man had allegedly been viewing the images from the bathroom for the last eight months. Police have seized the hard disk of his computer for cyber forensic examination.
Two married women, both sisters, whose husbands are working abroad, were living in the house with their children. The camera was detected by one of them and the police were informed.
Police said they were verifying whether he had fixed similar devices in other houses where he had installed water heaters.
