Patna, April 22: Unable to make any breakthrough in the murder of a 10-year-old girl in the state capital, police have decided to release sketches of a man who was seen chatting with the child at the Patna Sahib railway station from where she went missing two days ago.

Sketches have proved effective in solving recent cases of crime against women in the state, the police said.

The girl had come to the city with her mother and infant brother from Khagaria. She, and the toddler, went missing on Wednesday evening and her body was found in an onion cultivation field near the Bypass yesterday morning. Her one-and-a-half-year-old brother, who was unharmed, was found sitting next to her body, crying.

Patna City deputy superintendent of police Sushil Kumar said they are yet to make a breakthrough though a few persons have been rounded up.

“We are questioning a few persons whom we have rounded up. The girl’s mother had seen a person playing with the two children on the railway station premises. The man was listening to songs on his mobile phone and, according to the mother, had lured the children by letting them do so as well. The police will come out with a sketch of the person on the basis of the inputs and descriptions given by the mother. Once the person is taken into custody, we believe the case can be cracked,” Sushil Kumar said.

The police are yet to get the report of the post-mortem conducted at the Nalanda Medical College Hospital.

Police sources said the case was proving difficult to crack because no one knows how and when the children disappeared. “No one really saw what happened. That’s the problem,” an officer at the Bypass police station said.

The woman had arrived at Patna Sahib station along with her children and two other women on Wednesday morning to buy local cosmetics.
