"We have registered an FIR of robbery under relevant sections of the IPC and investigation is underway," said Station House Officer Shahid Ahmed.

In the police complaint, the woman said that three transgender persons visited her house and demanded money. She said her husband offered them Rs 2,100 but they demanded Rs 21,000. Even as they were negotiating the amount, one of the transgender persons allegedly snatched the wallet, containing Rs 10,000, from her husband and fled, the police said.
