A husband-wife duo was arrested on Saturday for allegedly killing their 15-year-old son in Chauri area in Bhadoi, police said.
Pintu Seth and his wife Rekha went to a government hospital on Friday evening claiming that their son Rahul hanged himself on a tree and committed suicide, they said.
However, Rahul's uncle arrived from Varanasi later in the day and lodged a murder case against Seth and Rekha, they said.
Rahul was first strangulated by his father Pintu and step-mother Rekha and they had later hung his body from a tree to make it look like a case of suicide, police said.
Both the accused have been sent to jail and further investigations are on, they said.
