A 22-year-old man beheaded his niece's lover and surrendered at the police station with the severed head in East Siang district of Arunachal Pradesh on Wednesday, police said.
The incident took place in the Ruskin area close to the inter-state boundary with Assam.
The accused, identified as Shibu Baishya, beheaded 19-year-old Ajay Das at a field and walked in the Ruskin police station with the severed head and surrendered himself, officer-in-charge C Joseph said.
