PESHAWAR, Feb 3: Police have registered FIR against four Taliban commanders for planning a car blast at Tela Band Bazaar near Badhber police station that killed 11 persons and injured 25 others on Wednesday.

Though investigators were still not sure about the identity of the accused, who executed the terror plan, yet a police official claimed to have found an important file from the blast site.

“The file can be helpful in recognition of the accused involved in the car bomb blast,” he said. However, a case was registered against four commanders of Darra Taliban.

“Four commanders of Darra Admakhel Taliban -- Tariq, Baba Khan, Siar Khan and Arif have been named in the FIR,” he added.

He said that Lashkar-i-Islam and Taliban had joined hands against the law enforcement agencies. They were trying to build up pressure on government to halt military operations in the tribal regions, the official added.

“The file, found at the blast site, contains several applications addressed to Khyber Agency-based militant group Lashkar-i-Islam for intervention in different disputes among the local people,” he said.

He said it seemed that an important member of the militant group had lost the file during the blast. It was also possible that the fleeing terrorist had thrown the file after getting puzzled, he added.

“We are trying to interrogate the applicants if they are found in the area,” he said, adding that LI was also involved in few others car bomb blasts in Peshawar.

The official said that several suspects had been interrogated but the actual culprit could not be apprehended so far. He said that policemen were deployed in plain clothes in different areas to arrest the culprit.

Other sources said that many police officers had changed their vehicles and preferred to move in private cars to avoid attacks.

The suicide attack on DSP Rasheed Khan on Jan 31 at Ring Road, they said, had panicked the officers. Policemen in all the circles had been directed to beep up security and keep vigilance on movement of suspected vehicles and pedestrians, they said.

“We are regularly receiving messages about movement of militants in Matani and Adezai areas but after sunset it becomes impossible for police to patrol the areas,” they added.

They said that it was need of the hour to equip police with latest armoured personnel carriers, heavy weapons and increase their manpower so that they could properly plug the entry and exit points connecting the tribal belt.

Rural Circle SP Abdul Kalam Khan said that police had controlled the area but presence of militants in some pockets of the suburban localities could not be ruled out as they could move quickly on sensing possible police raids.

He avoided giving further details.

However, he said that Taliban had already claimed responsibility for killing of DSP Rasheed Khan and warned of more attacks. The Wednesday's blast was a part of the series, he said, adding that the person, who owned the file, was identified but he was not involved in the attack.
