Painda Khan, a renowned chief of the Tanoli tribe took over the valley in 1834, but in 1841 it was restored by the Sikhs to Ata Muhammad, a descendant of the Mullah or Akhund Sad-ud-din. At annexation in 1849 Ata Muhammad was recognized as chief of Agror; but the arrangement did not work satisfactorily as Ata Muhammad khan conflicted with the British demands British. An expedition had to be sent in 1852 to avenge the murder of two officers of the Salt department; and in consequence of the unsatisfactory attitude of the chief and of repeated complaints by the cultivators, it was resolved in 1868 to place a police station in Agror and to bring the valley more directly under the administration of Government. This incensed the Khan of Agror, at whose instigation the newly built police station was burnt by a raid of The Black Mountain (Tor Ghar) Tribes, Akazais, Hassanzais, Chagharzais etc.
