Anjum, who was into a relationship with Sanjeev(24) of the same village, on last Saturday had gone to his residence where her family members landed up to forcibly carry her away from the boy's house, Moradabad SSP Vijay Singh Meena said.
Later, they locked the girl up inside a room in their house and subjected her to violent beatings, leading to her death on the spot, he said.
Shortly, after the incident came to light, the boy also allegedly committed suicide by consuming poison, they said.
A case of murder has been registered against Shauqat, his brothers Arif, Asif and Riyasat and two others Liyaqat and Riyaz in this regard, Meena said.
Further probes are on into the case, the SSP added.
