A 30-year-old man was arrested on Saturday for allegedly attacking a 15-year-old girl with a hammer and then raping her on railway premises in Ulhasnagar (east). The accused allegedly kidnapped her from the skywalk next to Ulhasnagar railway station last Friday, threatened her with a hammer and took her inside a room, where she was raped. The incident took place when the girl was returning home. She met her two friends on the skywalk and was speaking with them when the accused showed up. The accused, who knew the girls, allegedly hit the victim on the head with a hammer to threaten her. She suffered a minor injury on her head due to the attack. She then dozed off and got up in the morning when the accused had left. She escaped from the spot and informed her family about the incident. The accused has seven cases of theft and other offences registered against him. “The accused told us that he was convicted in a criminal case and came out after completing his punishment in 2018. He is from Ulhasnagar but relocated to Pune a few years ago and had returned some eight days ago,” said a police official. “The accused was produced in court and remanded in police custody until September 14,” said Valmik Shardul, senior inspector of Kalyan GRP.
