The burnt vehicles included 77 two-wheelers and eight cars, police inspector of Sinhagad police station B Kashid said.
It was a nightmare for the residents when they saw charred remains of the vehicles in the parking space of their respective housing societies, located in the same locality that also included a Pizza outlet where over 25 motorbikes parked outside the shop used by the delivery boys were gutted in the fire.
Police detained and interrogated a suspect, reportedly an anti-social element in the Sinhagad road area where Sun City is situated.
The culprits reportedly unplugged the petrol tubes of the vehicles and set them on fire between 3 AM to 4 AM, the residents said.
Based on the CCTV footage, police have issued two sketches of the suspects.
The city witnessed a similar incident a few months ago in Dhankwadai area where number of vehicles burnt was much less.
