Aurangabad acting superintendent of police Pranav Kumar told PTI that the Delhi police team rigorously questioned the father and brother of the accused, who hails from Lahankarma village of the district and is about 125 km from Patna, before returning to the national capital today.
The SP said that though the accused could not be caught, the police team has collected "vital" information which will help catch him soon.
The accused's father Saryu Singh and younger brother Abhay Singh were detained by the police and rigorously questioned at Tandwa police station last evening. They were later released, the SP said.
Meanwhile, residents of the village expressed deep anguish over what they felt was maligning of the name of the village by Thakur, the fifth accused in the gangrape of the girl in the national capital in a moving bus on Sunday.
Many of them even sought death sentence for Thakur for the barbaric act.
A stoic silence prevailed in Thakur's home which was broken time to time by cries of women of the family.
Thakur, son of a marginal farmer, studied in government school at Tandwa till matriculation before leaving for Chhattisgarh to work in some brew factory. He had landed in Delhi a year ago, the locals said.
