The father of the woman who shot three people and then took her own life at YouTube's headquarters on Tuesday warned police that his daughter hated the company.

Nasim Aghdam, 39, had told her family a few weeks ago that YouTube had 'stopped everything,' and 'she was angry,' Ismail Aghdam told The Mercury News.

Ismail Aghdam said the family called police on Monday to report his daughter missing after she failed to answer her cellphone for two days.

He added that he even warned police that she might be heading to YouTube's headquarters because she 'hated' the company.

On Tuesday around 2am, Mountain View Police called the family to report that they had found Nasim sleeping in her car and that everything was 'under control'.

Mountain View police confirmed to Mercury News on Tuesday night that a woman of the same name had been found asleep in a vehicle early Tuesday morning in a parking lot.

'Our officers made contact with the woman after the license plate of her vehicle matched that of a missing person out of Southern California,' said Mountain View Police spokeswoman Katie Nelson.

'The woman confirmed her identity to us and answered subsequent questions. At the conclusion of our discussion, her family was notified that she had been located.'

Ismail Aghdam described his daughter as a vegan activist and an animal lover.

According to state records, she had once established a charity called Peace Thunder Inc, to 'educate people about animal cruelty, environmental pollution' and other causes.

Nasim Aghdam had a significant online presence with multiple YouTube channels and social media pages. She posted an array of videos including workout clips, animal abuse videos and vegan cooking tutorials, reported the Mercury News.

In a video that Aghdam posted back in January 2017, she vented about her content being 'discriminated and filtered'.

She also said that her YouTube channel, which had more than 5,000 subscribers, used to get many views but claimed she started getting less when the company started 'filtering' her videos.

Aghdam's YouTube channels and social media pages were all removed in the hours after the shooting. She claimed she had at least four YouTube channels, one in English, and then others in Farsi and Turkish.

Officers and federal agents swarmed YouTube's headquarters complex just before 1pm after dozens of panicked employees called 911 to report gunfire.

Aghdam was a prolific YouTuber who had ranted online against the company's new policies and for 'censoring her videos and not paying her'

Upon arrival, police found the woman dead inside the campus with self-inflicted gunshot wounds.

San Bruno Police Chief Ed Barberini said three people were taken to hospitals in San Francisco with gunshot wounds.

A 36-year-old man was in critical condition, a 32-year-old woman was in serious condition and a 27-year-old woman was in fair condition following the shooting.

Television news footage showed terrified employees leaving the building in a line, holding their arms in the air for police to inspect as they were leaving the building.

Officers patted down people to make sure none had weapons as police vehicles surrounded the area.

Police did not release any further information on the suspect or comment on her possible motives for the shooting rampage.

The shooting had no known connection to terrorism, US government security officials said.

Her father told The Mercury News that the family did not know that Nasim owned a gun.

'Maybe she bought one' recently, he said.
