"We have no official confirmation on arrest of Maulana Masood Azhar," MEA spokesperson Vikas Swarup told ANI.
Also, Mohammad Zubair, a minister in Pakistan, told a TV channel that he could not confirm the arrest of Azhar by authorities, according to PTI.
Pakistan’s GEO TV claimed that Azhar's brother Abdul Rehman Rauf had also been arrested.
Though Lt Gen (Retired) Abdul Qadir Baloch, minister for frontier regions, confirmed that "Azhar was arrested".
