A man has been arrested after allegedly posting a YouTube clip where he appeared to be rehearsing a mass shooting from a downtown San Diego hotel room.
Steven Homoki, from California, US, was arrested on Thursday with 14 guns at his home, including three that were loaded and illegally modified.
The 30-year-old allegedly posted videos showing a series of different guns being pointed towards a hotel window in San Diego.
Police received a tip-off on Monday about the clips and stated Homoki had 'gone off the deep end' and had a 'plan' in place.
In the videos which were posted on YouTube in September, a female mannequin head can be seen sitting on the hotel room sofa with several assault weapons, magazines and bullets, inducing a hand gun as well as a machine gun.
The suspect was staying at the Sofia Hotel, which sits across the street from the San Diego courthouse, according to his arrest warrant.
The bodycam footage shows guns apparently loaded and the camera operator crawling on a bullet-strewn floor before re-loading the weapons and pointing them at pedestrians from the window.
The video begins with an unloaded hand gun being pointed at the window and fired as someone walks past.
Then an unloaded assault rifle is picked up and fired at another pedestrian, before another gun is aimed in the same direction.
The figure then walks around the hotel room before crawling around the floor picking up bullets to load them in a magazine, saying: "What do you do with this?"
At one point the trigger was pulled on an unloaded rifle aimed at passers-by and a voice said: 'One down, more to go.'
While running around the room with the assault rifle, the figure picked up what appears to be a bottle of spirits and repeatedly said, 'that's not true'.
The videos are reminiscent of the 2017 shooting in Las Vegas, where a gunman firing from a hotel room killed 59 people and injured hundreds.
Homoki told CBS in an jailhouse interview that he intended to post the videos privately on YouTube and never intended to hurt anyone.
He said: "It was just kind of like a miniature art project.
"I just wanted to relax, maybe do something a little fun and different."
Homoki is not being charged with making the video, but San Diego County deputy district attorney, Wendy Patrick, urged the judge to consider the 'simulated rehearsal for a mass shooting' when determining whether Homoki posed a threat to public safety.
Lieutenant Shawn Takeuchi of the San Diego Police Department said: "This video is very similar to that.
"You've got an individual manipulating weapons in a hotel room that overlooks downtown San Diego. So, that is very concerning."
Homoki remained jailed Friday on $20,000 (£15,216) bail after being charged with one count of suspicion of possession of an assault weapon, one count of possession of a high capacity magazine and one count of child endangerment.
He faces a maximum sentence of 10 years, eight months in jail if convicted of all charges.
Homoki is scheduled to be arraigned on Monday.
