He waited outside Sana Yousaf's residence for several hours before killing her in Islamabad's G-13 sector.
The accused confessed to the murder of Sana Yousaf.
The prime suspect is the owner of the production house, Bionic Films.
The unidentified assailant broke into the house and fired two bullets at Sana Yousaf.
Some individuals celebrated the murder and accused Sana of promoting vulgarity on TikTok.
According to initial police reports, unknown assailants forcefully entered her residence and opened fire before fleeing the scene.
Jannat's sister Alishba Anjum, also a well-known social media figure, joined her for the pilgrimage.
While acknowledging that anti-Muslim sentiment exists in India, Akhtar defended it by holding Muslims responsible.
“I like both mild flavors and spicy foods,” she noted, praising the diversity of taste in local dishes.
