However, a spokesman for the Jamaat-i-Ahmadiya Pakistan told Dawn that 95 people of the community had lost their lives in the strikes at Model Town and Garhi Shahu.
Punjab police spokesman DIG Akram Naeem Bharoka told reporters that 79 people had died and 107 injured in the bloody carnage.
Police obtained a 20-day physical remand of 17-year-old Abdullah alias Mohammad from an anti-terrorism court. The bomber was caught by worshippers and is in the custody of the Crimes Investigation Agency.
The other bomber, 20-year-old Mooaz from southern Punjab, who was earlier identified as Ameer Moavia, is being treated at Jinnah Hospital. He has been unconscious since Friday and underwent a CT scan.
Police arrested three suspects on information provided by Abdullah, of Rahim Yar Khan. Abdullah identified the two other men who blew themselves up in Garhi Shahu as Darwaish of Swat and Mansoor of Waziristan.
He told investigators that he and three others were sent for the two missions by Badar Mansoor, the head of the Punjabi Taliban group in Waziristan.
A police official said that Abdullah had provided valuable information to the investigators about other members of the network.
The Civil Lines police picked up six Afghan nationals on Friday night. DIG Bharoka said initial investigations suggested that four militants had reached Batti Chowk in Lahore from Miramshah via Bannu on May 21 and gathered at a nearby mosque.
They were taken by two facilitators to their potential targets for scouting out the place same day. They then left for Tableeghi Markaz in Raiwind, where they stayed under the pretext of attending Ijtima.
According to the DIG, the attackers stayed at Masjid Ibrahim on Ferozpur Road on May 26 and went to Batti Chowk on May 27, where their facilitators were already present.
One of the facilitators took Abdullah and Mooaz to Model Town and the other left for Garhi Shahu with Darwaish and Mansoor for a second scout-out. On May 28, the four men and their facilitators again converged on Batti Chowk and left for their targets on motorcycles. The attackers were provided heavy weapons, suicide jackets, magazines and detonators.
DIG Bharoka said the two facilitators, one of them identified as Rana, had provided logistic and weaponry support to the assailants.
Abdullah told the investigators that his younger brother Badar worked for the Tehrik-i-Taliban Pakistan and he himself got training from one Munir.
The DIG said that arrest of the two bombers had unearthed their network's link with the TTP and police would be able to reach others. He said that militants were in the habit of forming new groups.
