According to police, Manoj had thrown acid on an 18-year-old girl and her 16-year-old friend after the former refused his proposal for marriage. The victims were on their way to a market when Manoj attacked them last evening.
Police said Manoj is already married.

Passers-by had yesterday tried to catch the accused after he carried out the attack, but he had managed to flee the spot.
