The fast bowler's brother, Meraj, was arrested with two other men on charges of providing shelter to his uncle, Haji Daly, believed to be an active member of the banned Lashkar-e-Islam, the Express Tribune reported.
A local resident told the newspaper that a team of commandos raided the house on Tuesday.
Two paramedics, Younas and Shakil, were among those arrested. They were moved to an undisclosed location.
An official of the local police station claimed Haji Daly was injured in an operation by armed forces at Bara in Khyber tribal region, and had fled to Peshawar and lived with Meraj for several days before leaving the city.
The Khyber Agency is a stronghold of the Lashkar-e-Islam.
"The injured man was brought to Hayatabad medical complex with two local paramedics who changed his bandages," the official said.
The injured man left the hospital without his identity being ascertained, he said.
Reports indicated that the two arrested paramedics are employees of a maternity home located adjacent to Gul's house.
Gul's family owns the maternity home.
However, members of Gul's family declined to comment on the matter. A cousin of Gul confirmed that a raid had been carried out and three people were arrested.
