At least three golden crowns have been reported to be missing from Sri Govindaraja Swamy temple at Tirupati.
According to officials, the crowns collectively weighed about 1.3 kg.
The crowns adorned the statues of deities Lord Venkateswara, Sri Lakshmi and Sri Padmavathi at an ancient shrine inside the temple complex, they said.
A security official of the Tirumala Tirupati Devasthanams (TTD) told PTI that the crowns were reported missing on Saturday night.
He said surveillance camera footage was being examined to track the culprits.
The TTD has also filed a complaint with police who have started a probe, he said.
Police said they have registered a case but no arrest has been made so far.
