Idols of Lord Ganesh were immersed peacefully with religious fervour and enthusiasm in Hyderabad and other parts of Telangana on Sunday amid tight security.
Three people died in two different incidents during the festivities in Khammam and Medak districts.
While a nine-year-old child died after falling from a truck carrying the idol in Medak district, two teenagers were drowned in a lake in Khammam district while immersing the idol.

The mammoth procession, which began from Balapur on the city outskirts, passed through the communally-sensitive old city and the main thoroughfares while proceeding towards the Hussain Sagar Lake.
Police said no untoward incident was reported from anywhere in the city. The afternoon and evening prayers at the historic Makkah Masjid near Charminar passed off peacefully amid tight security and vigilance by the police.
More than 30,000 policemen, including personnel from the central paramilitary forces, were deployed in both Hyderabad and Cyberabad police commissionerate limits as part of the elaborate security arrangements.
Police forces were drawn from neighbouring states of Andhra Pradesh and Chhattisgarh also in addition to nine other districts of Telangana to oversee the culmination of the 10-day festival in Hyderabad.
