A man walked for a kilometre with the severed head of another man he had killed before surrendering to the police in Assam's Lakhimpur district on Wednesday, police said.
Nikodin Tiru of the Dolohat tea estate killed Salu, a traditional medicine practitioner, and beheaded him with an axe at Phulbari No:1 Sarang village.
Tiru then took the severed head and walked with it to the Dolohat police outpost where he surrendered.
Tiru claimed during interrogation that he was suffering from mental problems and had approached Salu in November to cure him but there was no improvement in his condition.
He further alleged that Salu was planning to take away his land and other property following which he had killed him in a fit of rage, the police said.
Tiru has been arrested and further investigations have been launched, the police said.
