Bhola: Two sisters sustained serious burn injuries as unidentified miscreants threw acid on them while they were sleeping at Uttar Digholdi in Sadar upazila on Monday night.

The victims were identified as Tanjim Akhter Mala, 16, and Marzia, 8, daughter of Mohammad Helal of the area. Mala is an A-grade student of the Abdul Mannan Secondary School of the union, and Marzia is a student of class 2 of another local school here, reports the UNB.

Victims’ relatives said the two sisters went to sleep after taking their dinner Monday night. Suddenly, family members got up hearing their screaming, as someone had thrown acid through the window around 2:00am, leaving the two sisters critically burned in the face, eyes and some others parts of the body.

The family members took them to Sadar Hospital from where they were transferred to Barisal Medical College Hospital on Tuesday as their condition deteriorated, said Md Taibbar Rahman, duty doctor of the hospital.

Stalker Rajib used to disturb Mala over mobile phone for long, although she rejected his proposal of love. Rajib could have thrown acid on them as his reaction, victim’s family reasoned.

Soon after the incident, police arrested two people in this connection, Md Moktar Hossain, Superintendent of Police in Bhola said.
