Hammad Adil also told the police that a suicide bomber was on his way from the tribal areas to Islamabad to launch another attack on a major installation in Islamabad, the Express Tribune reports.
Islamabad police had arrested Hammad Adil two weeks ago in a raid, along with Muhammad Tanveer, an alleged TTP ringleader and a car laden with explosives, from their hideout in Phulgran in Islamabad's suburbs.
The confession by Adil came at a time when the police had given up the tracing of Bhatti's killers.
Bhatti was gunned down in the capital in March 2011 outside his residence, where the militants forced his vehicle to a halt and opened fire.
These two were suspected of planning the attack on Bhatti with the help of another accomplice, Omer Abdullah.
Adil is said to be among the planners, while Tanveer allegedly provided them with the AK-47 and other weapons used in the assassination, the report added.
