The vehicle in which the victims were travelling on the Jewar-Bulandshahr highway on the intervening night of May 24 and 25.
In the early hours of Thursday, armed men struck a group of eight people travelling to Bulandshahr in a vehicle on the Jewar-Bulandshahr road off the Yamuna Expressway, shot dead a man, raped four women and took away cash and jewellery.
A special task force of the police on Friday afternoon picked up five men for questioning in connection with the gunning down of a man, gang rape of four women and alleged robbery in a field off the Yamuna Expressway
in Uttar Pradesh in the early hours of Thursday. Police had detained the five for questioning on Thursday night, but let them off later.
Initially, police said, the five were questioned because one of the women told media that she had identified three of the six assailants as her neighbours. She, however, retracted the statement a day later.
The FIR that was registered on the statement of one of the men in the vehicle in which seven others, including the women, were travelling said the suspects were stranger to them and the women could recognise them.
