Arshad said soon after the attack on the Sri Lankan team in Lahore, law enforcement agencies had picked up Khosa and his elder brother but they were later released.
He said Khosa later went to Dubai. Arshad claimed Khosa had had no contact with his family for the past few years. In a separate development, police arrested two suspects in connection with an attack on a Shia procession in Lahore.
Qari Mustafa and Commander Ameen were picked up from a neighbourhood in Lahore for their alleged support to suicide bombers.
Three suicide bombers had targeted the Shia procession on September 2 last year, killing at least 35 people and wounding 200. Explosives, suicide jackets and sophisticated weapons were recovered from the two arrested men, officials said.
