ANIMAL rights vlogger Nasim Aghdam who shot three staff at YouTube's HQ hated the site for censoring her videos.

Aghdam, 39, stormed the offices in San Bruno, California, on Tuesday leaving a man and two women injured before turning a handgun on herself.

On her website and YouTube account, Aghdam complained fans could hardly see her videos because the company filtered her content.

Cops don't believe the shooting was terror related and are working on the theory it was a domestic incident.

Aghdam’s 36-year-old boyfriend is reportedly one of the victims and is fighting for life in hospital.

Her dad Ismail Aghdam said he warned police that she "hated" the company and might be heading there.

Sources told NBC that Aghdam was a prolific poster to her YouTube channel on which she ranted about not being paid and the video streaming service's "dictatorial" censorship policies.

Posting videos under the name “Nasim Wonder1,” she describes herself as: "A well-known and most famous animal rights activist in Persian/Turkish community."

She also calls herself: "A Persian Azeri female vegan athlete and animal rights activist promoting VEGANISM, the healthy and humane way of living."

Her most recent post came three weeks ago and was titled Leg Exercises At Home Fitness.

In another video, posted by NBC reporter Vicky Nguyen, Aghdam complains about being “discriminated and filtered on YouTube".

Last February she posted a picture of herself holding a home-made protest sign which read: "Youtube dictatorship. Hidden policy: promote stupidity, discrimination, suppression of truth."

The clips have since been scrubbed and her account has been deleted.

The area was placed on lockdown following reports of shots being fired shortly before 1pm local time.

Two women, aged 32 and 27, were shot and in a fair to serious condition.

Ed Barberini, San Bruno Police Chief, told reporters: "Police were alerted at 12.46 to numerous 911 calls about gunshots at YouTube HQ.

"Police arrived 12.48 and immediately began search for shooter.

"We encountered numerous employees fleeing from building.

"We saw one victim with gunshot wound towards front of business as we arrived.

"Officers then moved inside and located a second individual with gunshot wound which appears to be self inflicted."

Police Chief Barbarini described the "monumental task" of locking down the area to interview all witnesses.

He said there were "numerous" agencies on the scene and said it was too early to speculate on a motive.

Project manager Todd Sherman tweeted: "I looked down and saw blood drips on the floor and stairs.

"Peaked around for threats and then we headed downstairs and out the front."

Sherman said he initially thought the sound of people running was an "earthquake" before realising a shooter had stormed the building.

He said: "We were sitting in a meeting and then we heard people running because it was rumbling the floor. First thought was earthquake.

"After existing the room we still didn’t know what was going on but more people were running.

"Seemed serious and not like a drill.

"We headed towards the exit and then saw more people and someone said that there was a person with a gun. S***.

"At that point every new person I saw was a potential shooter.

"Someone else said that the person shot out the back doors and then shot themselves."
