Faisal Wada was returning home from the National Accountability Bureau (NAB) office when unidentified men in a car fired at least four to five shots at his vehicle.
Imran Ismail, another party leader said whose car was behind Wada's vehicle, said, "The armed men fled in their car after my guards opened fire on them in retaliation."
In May 2013, PTI Vice-President Sindh chapter, Zahra Shahid Hussain, was killed in an attempted robbery incident on the eve of re-polls in Karachi's NA-250 constituency.
