A passerby found the body hanging from a tree and informed police, who went to the spot and recovered it.
The body was later identified as that of Ram Fere, a resident of Hardoi.
Police have recovered a suicide note, which states that his employer was not responsible for his death.
"There is no signature of Ram Fare on the suicide note, which indicates that somebody has written this note before killing him. However, police are investigating the case from all angles," a police officer said.
