Could you guys help me on this one?

"Başka bir görüşe göre de Mahidevran Sultan´un Şehzade Mustafa´nın Veliaht sancağından alınmasından sonra Şehzade Mehmed´in Veliaht sancağına atanmasını kaldıramamış ve Barbaros Hayrettin Paşa´ya haber vererek genç şehzadenin haremine güzel ama hastalıklı bir cariye sokmasını emretmiştir."

According to one more theory... and the last part is about stinging someone with a knife, right? But I can´t actually find the subject in this sentence  

According to another view, Mahidevran Sultan couldnt accept the appointment of Prince Mehmed to the state of the heir after the removal of Prince Mustafa and she wanted Barbaros Hayrettin Pasha to place a beautiful but diseased female slave to the harem of the prince.
