Vaidya was the second runner-up in the first season of the reality show Indian Idol.
The incident came to light when the Vaidyas, after returning from Europe yesterday, discovered Rs 25,000 in cash and imitation jewellery worth Rs 15,000 missing from the cupboard in their house located in Samarth Angan building in suburban Andheri, they said.
The Vaidyas were in Europe from June 1 to June 12 and the crime took place in that period, police said.
The main door of the house was intact but the bedroom door and the cupboard were found damaged by the robbers, they said.
"The robbers seemed to have opened the door using duplicate keys. The crime took place between June 1 and 12 and we are checking the CCTV footages in the building premises," an investigating officer said.
Vaidya's father Krishna lodged a complaint at Oshiwara police station last night, they said.
Incidentally, actor Anuj Tikku's father Arunkumar was murdered in the same building on April 7 by dreaded criminals Vijay Palande, Dhananjay Shinde and Manoj Gajkosh, all former associates of gangster Santosh Shetty. The trio is in jail for the killing.
