BANGALORE: Pulled up for defying her mother's strictures against using mobile phone, a 15-year-old girl committed

suicide

late on Tuesday evening by hanging herself from the roof of her house in Valmikinagar of Chamarajpet.

This is the third incident of a teenager embracing death for frivolous reasons in two days.

Hours before she was found hanging,

Sumaiah

Mohammed, a Standard VII student of a Tamil school near Toll Gate on Mysore Road, and daughter of a mutton stall employee, had a heated exchange with her mother

Salma

, for speaking to her friends on the mobile for long hours

After having failed to dissuade the girl from chatting, Salma had recently removed the SIM card from the mobile phone.

On Tuesday, the mother of five was doubly furious with Sumaiah after having caught her speaking on the phone using a SIM card she had got from a classmate. "How dare you cheat me, that too at this early age," Salma is said to have told Sumaiah before leaving for the market at 7pm.

Sumaiah was alone at home as her two brothers had accompanied their father, Syed Mohammed, to his workplace in KR Market, and her two sisters were playing in the neighbourhood. Hailing from Tamil Nadu, Sumaiah's family had settled in Valmikinagar for 10 years.

Around 8pm, a neighbour, Fatima, knocked on the door. When she received no response, the woman called Salma on her phone and told her something was amiss as Sumaiah, who was at home, was not opening the door.

Salma rushed home and with the neighbours' help, broke the door open to find Sumaiah hanging from a beam in the roof. Sumaiah has not left behind any suicide note.

"We strongly suspect the conversation between Salma and Sumaiah ended in the tragedy. But we cannot blame Salma. We are investigating,"
