KARACHI - Unidentified men attacked a PPP office with a hand-grenade here in Mawatch Goth in the Maripur Police precincts on Friday. The explosion damaged walls of the office while no causality was reported. The PPP PS-90 office, located in Sheikh Mohallah, Mawatch Goth, was attacked with a hand-grenade by unknown culprits. Following the explosion, a heavy contingent of law-enforcement agencies, accompanied by Bomb Disposal Squad rushed to the scene.

According to the BDS officials, the attacker had attached pebbles with the cartridges of a rifle and that it was not a hand-grenade attack as claimed by some PPP office-bearers. PPP MNA Abdul Qadir Patel usually visits the office and receives applications and complaints from party workers in the office. According to Bashir Baloch, PPP PS-90 President, the main gate of the office was permanently closed and visitors come through an alternate gate. The attackers might have thought MNA Patel and others local leaders as their target because they usually visit the office, he said. He demanded the Police officials to curb the target-killings and provide security to citizens. He also claimed that the office was attacked with a hand-grenade. It was obviously a hand-grenade, he emphasized. The Investigation Officer (IO) said that the attack was carried out by unidentified miscreants who were riding on bike(s).

It is to be noted that in the recent past, two close-aides of PPP MNA Abdul Qadir Patel have been targeted in the area including Edhi Ameen, personal assistant to the PPP MNA.
