"The girl hanged herself from a fan at her house last night," assistant sub-inspector A N Mishra said.
The 17-year-old youth, who often followed the girl to her school and a coaching centre, approached her last evening and forced her to take a mobile phone and asked her to be in touch with him, Mishra said.
When the girl complained to her parents, they ticked him off, which led to a heated argument between the two families, the police officer said.
Amid the quarrel, the girl ran inside and hanged herself after locking herself in a room.
Her parents broke open the door and rushed her to a hospital where doctors declared her brought dead, Mishra said.
Police apprehended the youth under the IPC section 306 (abetment of suicide) and further investigations was on, said inspector Arvind Jain of the Civil Lines Police station.
