A man from Punjab's Muzaffargarh district murdered his three minor daughters and wife on Saturday over suspicions that she had 'illicit relations' with someone, police said.

The incident took place in Seetpur town of the district in the early hours of Saturday, according to police.

The man, after committing the brutal crime, turned himself in before the police, and handed over the knife which he had allegedly used to slit the throats of the four deceased, police officials told DawnNewsTV.

The bodies of the minor girls — the youngest of whom was less than a year old and the oldest aged around 10 — along with their mother were shifted to the hospital for a post-mortem examination.

The suspect, who is currently under police custody, confessed he had committed the murder as he had "doubts over his wife's character".

A case has yet to be registered against him.
