The incident occurred at their house located in Shershah locality.
The three brothers, Rizwan, Faizan, Noman and their friend, Zohaib, were arrested by the Shershah police, who have registered a FIR under Section 302/34 against them on behalf of the state.
The brothers admitted to the crime, however, all the arrested suspects defended themselves and told the police that their father had a 'bad character' because of which one of their sisters was not safe from him. They accused their father, Shakeel, 51, of attempting to abuse one of their sisters, which is why they killed him.

"We didn't want to kill him but he [our father] compelled us to kill him with a knife while we were attempting to save our sister from him. He [Shakeel] was killed mistakenly during the scuffle. It was totally unintentional," they said in their statement to the police.
"We already complained to the police in 2013 against our father over the same matter at the same police station," they said.
The arrested brothers told police that they belonged to Peshawar where their father had also been arrested in a similar case.

The officer said police had taken action following the suspects' complaint against their father in the past, but their father had gone underground.
