On the right and left side of the palace entrance there were two officers on watch with the same armament. On April 10, an hour before the arrival of the Shah, a plainclothes officer from a special unit came into the palace grounds. Another non-commissioned officer of this special unit named Laschgari was already in the palace. The guard Shamsabadi was on duty that day and was assigned to a guard position in the triangle in front of the palace. Shamsabadi was considered a particularly good marksman. As it later turned out, Shamsabadi had been contacted by opponents of the Shah while on home leave and won an assassination attempt.
