Failing to endure insults by her "stalker", a schoolgirl allegedly committed suicide by taking toxic chemical in Gaibandha's Sadullapur on Tuesday night. 

Ayesha Siddiqui Misty, 14, daughter of Mostafizur Rahman of Chalk Durgapur village, was a class nine student of Matherhat Girls High School.

Quoting the victim's family, Inspector Motiur Rahman, in-charge of Dhaperhat Police Investigation Centre, said Sohel Mia, 20, of the same village, had been stalking Ayesha on her way to and from school for the last two years. Guardians of both families sat several times to stop it, but to no avail, the police official added. 

On Tuesday afternoon, when Ayesha was returning home from school, Sohel along with some associates intercepted her on Matherhat bridge and asked her to develop an affair with him. Refused, Sohel assaulted her and also threatened to kidnap her.

Hearing her screams, locals came to rescue Ayesha, but the "stalker" and his associates fled.

Following this, Ayesha took a bottle of oil meant for dyeing hair around 8:00pm and died on the way to Sadullapur Upazila Health Complex. The oil contained poisonous substance, said Farhad Emrul Kayes, officer-in-charge of Sadullapur Police Station.

A case was filed against six people, including Sohel, with the police station.

Police arrested Sohel's three associates -- Ashraful Islam, Majed and Farid. But main suspect Sohel was on the run.

Locals demanded immediate arrest of the "stalker" and all of his associates and sought exemplary punishment for them.

Police were trying to arrest Sohel, OC Farhad said.
