An unmarried couple was found hanging from a tree in Safdarjung area of Barabanki district on Friday, police said.
According to Assistant Superintendent of Police Ashok Kumar, prima facie it seems to be a case of suicide as both were in a relationship and their family did not give consent for their marriage since both belonged to different castes.
"We will conduct a probe to look in the incident", the official said.
The duo, who had allegedly gone missing on Thursday night, was found hanging from a tree next morning.
The bodies were sent for post-mortem and an investigation in the matter is underway.
