In a series of videos posted to Twitter by eye-witnesses, a shirtless man could be seen climbing to the top of the park’s Supreme Scream ride.

One video showed the man halfway up the structure while PM Breaking News reported that he could be heard “screaming” from the top of the ride.

At least two other clips posted by onlookers filming from a distance captured the man appearing to wave his arms around while the area around the ride was evacuated.

Local news cameras later picked up shots of the man sitting calmly on top of the ride with his arms outstretched.

Adrian Placencia was among those at the park who witnessed the dramatic events unfold first-hand.

He told Newsweek: “My sister and I were resting on a bench when we suddenly saw a man hurriedly cross the crowd at one of the plazas at Knotts, as if he was anxious to get somewhere.”

“He was covering half of his face with his shirt, had a large backpack on, and was also very dirty, with soiled baggy clothing. His eyes were wide open and his movements were a bit unnatural.”

“My sister and I disregarded the situation, even though we found it odd and decided to go on the “Supreme Scream” ride,” he continued.

“Upon arriving, we noticed that there was a large crowd beginning to form with people taking out their cellphones and pointing them in the direction of the ride. To our surprise, the same man we saw earlier, had jumped over the boundaries, and began to climb the ladder used for emergencies and maintenance.”

“Everything happened very quickly,” Placencia said. “People were confused, as we didn’t know who the man was, or what was going on.”

While staff and onlookers rushed to notify the authorities, he says that there was a notable change among those watching on as it became clear “this was no park-related stunt.”

“The emotional reaction of spectators at the park shifted from curiosity to concern,” he said.

“People began leaving the scene, including I, because there was a possibility that the man was there to jump. Not only was it dangerous if he did, but the emotional burden of the possibility was enough to defer most park-goers to leave.

He added: “As we walked away, glancing at the tower periodically, we noticed the man had finally reached the top, and was actually trying to reach for the American flag located at the tip. He then gave up, and proceeded to sit down, pound his chest, stand up, dance, and more.”

Police spokesperson Sgt. Mario Escamilla told the Orange County Register that the alarm was first raised when park visitors flagged down an officer at around 7:22 pm and pointed out the man climbing up the ride.

Buena Park Police then arrived at the scene along with the Orange County Fire Authority while La Palma Avenue was temporarily closed between Beach Boulevard and Western Avenue.

Police subsequently issued an appeal to the public on social media to “please stay out of the area while we work to bring this person down, safely.”

Though the park stayed open, the area around the Supreme Scream was cordoned off with firefighters preparing to conduct a technical rescue.

Ultimately the man climbed down of his own accord with Buena Park police confirming, at around 9 pm, that “the subject has come down safely.”

Officials from Orange County Fire Authority later tweeted: “Once the individual was secured, our firefighter paramedics assessed and transported him to a local hospital.''

Sgt. Mario Escamilla told the Orange County Register the man would be undergoing a mental health evaluation.

It remains unclear how the unidentified individual managed to climb to the top of the ride or whether he will face any criminal charges as a result of his actions.

Responding to the incident, Knott’s Berry Farm said in a statement: “Knott’s Berry Farm became aware of a male who had accessed an unauthorized area and climbed the Supreme Scream tower.

“Park personnel alerted local law enforcement and emergency responders who are now on site. The guest descended the tower at 8:55 p.m. and is now currently safely on the ground in police custody. No other information is available at this time. The safety of our guests is always our top priority.''

The incident comes just over a week after a drive-by shooting took place outside the park.

Two teenage boys were injured in the attack, which took place on July 9.

Newsweek has reached out to several eye-witnesses and Knott’s Berry Farm for comment.
