DSP Fateh Mohammad along with two police guards and a driver were on routine patrol when their car was attacked by four bike-borne militants in Gulshan-i-Hadeed area of the city, a police officer said.
Following the attack, the militants managed to escape on their bikes. A manhunt was initiated to nab them, the officer said.
Meanwhile, Tehreek-i-Taliban Pakistan spokesman Mohammad Khurasani claimed responsibility for the attack, saying it was carried out to avenge the killing of militants in Karachi.
