Veterinary doctor Ashfaq Ahmed, 68, was shot dead on Friday in the Lalazar area of Lahore in what appeared to be a faith-based targeted attack.
The doctor was being driven by his nephew when a motorcyclist pulled up next to their car and fired at point-blank range, killing him on the spot.
His nephew, Shahzeb, remained unhurt, while the attacker, who was wearing a helmet, fled the scene.
Dr Ashfaq Ahmed had retired as a professor from Lahore University of Veterinary and Animal Sciences. He held a PhD in food and nutrition.
For the police, it was too early to say whether he was targeted because of his faith.
