A 14-year-old girl committed suicide by hanging herself at her house on Tuesday after her boyfriend allegedly dumped her via a Facebook post.

In her suicide note, the girl held her boyfriend responsible for her action. The police have arrested the boyfriend, a second year B.Com. student at a Bangalore college.

The girl was the eldest daughter of a lecturer. Her mother worked with a private firm.

According to the police, her mother returned from work and found the door locked from inside. When nobody responded to the doorbell, she sought the help of neighbours to break open the door and found her daughter hanging.

The police found a three-page suicide note in which the girl said she had opened a Facebook account in August this year. She said the boy had sent her a friend request and she accepted it. Soon they started chatting regularly and the friendship turned into a relationship.

On October 14, the boy invited her to his house in Nandini Layout. They started having a physical relationship.

The girl said the boy had recently become indifferent to her. She accused him of wanting her friends’ mobile numbers too. When she confronted him, he allegedly replied that he had a physical relationship with her only for fun. He then said he couldn’t marry her as he had promised to marry a girl of his parents’ choice.

He sent her a message to this effect, which prompted her to take the extreme step, the police said.

The girl’s mother told the police that her daughter did not have a mobile phone nor a computer at home. She would use the local cyber cafe regularly and once had used her phone.

Unaware of the developments, her mother had called the boy and had warned him to stay away from her daughter, thinking he was trying to woo her.

The girl requested the police to take strong action against the boy and advised her friends to avoid using Facebook, the police said.
