Just last week, an FIR was lodged at the Sinthee Police Station after a mountain bike was stolen from inside a housing complex in Roypara area, a senior police officer said.
"The owner, a woman, had parked the bicycle inside the premises of her apartment after locking it. But, the two- wheeler was gone the next morning," he said.
Behala resident Sumit Chakraborty said his brand new bicycle, which he had recently bought to commute to office in Jadavpur area, was stolen from his house, where it was parked.
Around 87 such complaints have been received since the beginning of June, the police officer said.
