No arrest has been made so far," Panday said.Sahil, who hails from Bhopal, sustained minor injuries while the woman, from Bijnore in Uttar Pradesh, escaped unhurt. Their car was also damaged by the mob and was later towed to the police station.The trouble began when the couple reached the sub-registrar's office. When they were filling up a form, some men in the office noticed that the man was a Muslim and the bride a Hindu.Some men reportedly began asking them embarrassing questions. When the couple protested, a dozen men started thrashing the man. Police personnel stationed at the compound saved them and eventually helped them to leave.
