Pakistan Army on Saturday took control of the Karachi Police Office and its teams started investigation into the Friday's terror attack as the three assailants have been identified, reported 24NewsHD TV channel.

Pakistan Army investigation teams examined the incident site. The snipers of the Army were still deputed on rooftops and around the Karachi Police Office. 

The alleged terrorists who were involved in the audacious attack on the Karachi police compound last night have been identified. 

One militant who blew himself up during the storming of the police compound has been identified as Zala Noor, resident of North Waziristan and the other terrorist who was shot dead by the firing of security forces was identified as Kafayat Ullah. He hailed from Lakki Marwat. The third terrorist was also a resident of Dattakhel in North Waziristan.

Investigation points to security lapse 

Meanwhile, the investigation into the militant attack on the police building was underway. 

The initial investigation points to a security lapse. At the time of attack, Investigators discovered that there were no proper security arrangements.

The terrorists entered the compound through Police Lines. They jumped over the back wall and broke into the building. 

Sources said there was no security on the entry and exit points of the Police Lines Quarters. No CCTV cameras were installed there. There are 150 quarters in the Police Lines in which police officials reside with their families. 

The report compiled by the bomb disposal squad said that its personnel had conducted a thorough search from the ground floor to the fourth storey of the building.

The mechanical suicide vests were prepared based on suicide detonators system and there was no electronic system installed in them.

Owner of car used in attack arrested

Personnel of law-enforcement agencies have arrested the alleged owner of the car used by the terrorists for attacking the Karachi Police Office.

The car owner was arrested during a raid in Bhains Colony No 6.

In his statement recording to the investigators, the owner said he had sold his vehicle to a showroom. “I don’t know to whom the showroom sold the car,” he added.

A Pakistan Taliban suicide squad stormed a police compound in the port city of Karachi in which three militants were killed while two policemen, one Rangers official and a citizen embraced martyrdom on Friday evening.

At least 19 men, mostly police and Rangers officials, sustained injuries in the exchange of fire with militants who stormed the heavily guarded Karachi Police Office after lobbing a hand grenade at its main entrance, police and hospital officials said.

Security forces launched an hours-long operation and cleared a five-storey police compound last night. 

During the operation, two terrorists were killed in a direct fire while the third was killed when his suicide jacket blew up from a sniper fire.

A spokesperson for the Sindh Rangers informed that the operation had been completed and the process of clearing the area was underway.

The attackers equipped with the latest automatic weapons besieged the police headquarters and started indiscriminate firing. They also propelled two hand grenades into the building while trying to break into the office.

Earlier reports suggested that at least 8-10 terrorists entered the police office and an exchange of fire continued for hours with many explosions heard from the building. 

The outlawed TTP on the social media claimed responsibility for the latest ambush, which came as a grim reminder of attacks on Bannu CTD complex and Peshawar Police Lines mosque in recent months. The Taliban warned Saturday of more attacks against law enforcement officers, a day after attack on police compound in Karachi.

"The policemen should stay away from our war with the slave forces, otherwise the attacks on the safe havens of the top police officers will continue," Tehreek-e-Taliban Pakistan (TTP) said Saturday in an English-language statement. "We want to warn the security agencies once again to stop martyring innocent prisoners in fake encounters otherwise the intensity of future attacks will be more severe."
