Tehrik Galba-e-Islami has claimed that it carried out the attack on policemen at Khilwat junction in Old City on Friday.
The same organisation left a statement written on a piece of paper at Falaknuma after firing at a police picket killing a home guard and injuring a constable on May 18 last year on the second anniversary of the blast in Mecca masjid.
The statement, containing more or less the same content, was found in the CD, police sources said. In both statement, the name of Mohammad Fasiuddin was mentioned. Police are clueless about Fasiuddin and the TeGI.
The content in the CD said the attack on policemen was in retaliation to the bomb explosion in Mecca masjid.
