A 36-year-old sub-inspector has been booked for allegedly beating a man who accompanied a complainant in a kidnapping case to Mahim police station here, an official said on Sunday. The incident took place on Friday when sub-inspector Gahininath Satav was on night duty. Ganesh Jalgaonkar (55), a Western Railway employee residing in Mahim Causeway area, went to Mahim police station along with his neighbour Nadeem Sheikh to find out about the progress made in Sheikh's complaint of his two minor children going missing, the police official said.

Sheikh had filed a police complaint after his children went missing from home on Wednesday. When Sheikh and Jalgaonkar went to the police station on Friday around 3 am, Satav asked them why they were sitting there. The two men told him they had come to enquire about Sheikh's missing children, the official said. Jalgaonkar then allegedly abused Satav, following which the latter slapped him, he said. Satav also asked a constable to lock Jalgaonkar in a room where he again allegedly slapped him. In the process, Jalgaonkar's head hit a table, causing bleeding, the official said quoting the man's complaint.
