(KGTV) - Two teenagers could land in trouble following their daredevil actions atop the Golden Gate Bridge, made public earlier this month.
The video first posted on May 7 on YouTube, by the user Peter Teatime and Tommy Reactor, shows the pair climbing the 750-foot San Francisco bridge without any safety gear around dusk.
Both scale the bridge's suspension cables to the top, where they spent some time hanging off the sides of the bridge, doing flips, and climbing across the top.
According to the Golden Gate Bridge, Highway and Transportation District, the duo went unnoticed because they didn't trip any alarms on the bridge.
The Golden Gate Bridge, Highway and Transportation District said changes to bridge security are currently being implemented.
"This incident raises questions about how such an unauthorized climb was possible and the potential harm to drivers below if one of the climbers had fallen onto the roadway," Priya David Clemens, of Golden Gate Bridge, Highway and Transportation District, said.
Clemens said the district is now working with Homeland Security, the California Highway Patrol, and other agencies to investigate the incident. The investigation is ongoing.
"Our dedicated patrol officers, sergeants and lieutenants do an excellent job protecting the structure and stopping suicidal individuals every day. The reckless behavior of the individuals who performed this stunt does not distract from this fact," Clemens said.
The incident is similar to one that occurred four years ago.
In that incident, the suspect was placed on a "Do Not Fly" list by federal partners and ultimately lost their job.
