According to the FIR registered with Waryam police station, accused Asmatullah, a resident of Battimanjer village of Bhakkar district, had sent a marriage proposal to the girl's father Haq Nawaz through his friend Touseef but he rejected it.
Following this, Asmatullah, along with Touseef, entered Nawaz's house and allegedly threw a bottle full of acid at his daughter, wife Mumtaz and son Abbas who were sleeping on the rooftop of their house and fled.
Doctors said Shabnam suffered severe burns on her face, particularly her eyes.
"She has lost her both eyes," they said.

He also ordered best treatment for the victims.
The acid throwing incidents on women are on the rise especially in Punjab, a province of 90-million people.
