According to police, four armed men intercepted SAMAA TV journalist Shahzad Iqbal and opened fire on him in Mianwali town, some 300 kilometres from Lahore.
Iqbal suffered multiple bullet wounds and was shifted to hospital where he was pronounced dead on arrival.
District Police Officer (Mianwali) Mujahid Akbar told PTI that Iqbal, 28, had an enmity with Bashir Ahmed and his brothers over a (woman) issue.
He said the deceased family had named Bashir and his three brothers in the FIR.
Iqbal had been in the journalism profession for the last seven years or so and he worked for different publications during his career.
The DPO dismissed the reports that Iqbal lost his life in a terror attack.
