A 16-year-old boy allegedly hanged himself at his residence in Kolivery locality in Santacruz here apparently over his one-sided love affair, police said on Sunday.
The incident took place on Friday.
Before ending his life, the boy had sent on WhatsApp a goodbye message to the girl he was in love with, police said.
"The boy was a Class XII student. On Friday, when the boy's family members left home for work, he locked himself up. Soon afterwards, one of their woman neighbours knocked at their door, but as there was no response, she peeped through the window when she saw the boy tying a noose inside," an official of Vakola police station said.
"As she raised an alarm, the nearby residents came to the spot and broke open the door. However, by then the minor had hanged himself," he added.
He was rushed to a nearby hospital, where he was declared brought dead.
The boy's father told the police that when he checked the boy's mobile phone later, he saw that his son had sent a WhatsApp message to the girl he was in love with. The message in Hindi read- 'I will leave. I won't trouble anyone', the official said.
The boy had even tried calling many of his friends before ending his life, but none of them had picked up his call, he added.
The police have registered an accidental death report (ADR) in the case.
