Is there any legal responsibility after selling a spy pen camera? Could the police harass the shopkeeper for selling such a product?

There’s no specific law prohibiting the sale of spy pen cameras in India. However, if the camera is used for illegal activities like recording private conversations without consent, the seller could be held liable as an accomplice. Police can’t harass a shopkeeper solely for selling a spy pen camera, but they can investigate if there’s evidence of its use in illegal activities.
