The arrests were made on the basis of statements given by the women, who have undergone medical examination, he said.
The crime took place some 60 km from Noida, on the Jewar-Bulandshahr highway around 1.30 am on Thursday, when eight members of the Greater Noida-based family, including the four women, were headed to Bulandshahr to visit a relative.

When scrap dealer, Shakeel Qureshi, put up resistance, the men shot him dead. The victims were also looted of their valuables, mobile phones and Rs 47,000, the police said.
