The deceased has been identified as Amit, who lived in a rented accommodation in Ghaziabad, they added.
"Police received information this morning, that a man was hanging from a tree in Sibapur area. A police team was sent to the spot," a police officer said, adding we could establish his identity from the documents recovered from his pocket.
Some injury marks were found on Amit's body, a native of Azamgarh district, which suggests that he might have been murdered before being hanged from the tree, he said.
