Gwalior: A 20-year-old man hanged himself at his house in Hazira area on Tuesday after allegedly killing a 15-year-old boy.
The man had accused the boy of establishing a homosexual relationship with him and blackmailing him.
The body of the boy with his mouth and feet taped was found in the Gwalior city of Madhya Pradesh on Thursday, police said.
It is suspected that the man, a make-up artist, might have killed the boy before taking his own life.

The boy's body was found on the premises of the old JC Mill in the city. A make-up kit was found near it, suggesting the man's involvement in the murder, said another official.
The boy's body has been sent for post-mortem and its report would throw light on the cause of death, Mr Sanghi said.
