Four men involved in a skydiving stunt from the top of New York's One World Trade Center last year have been arrested and charged.
A video of the 11 September jump has had hundreds of thousands of hits on YouTube.
"These men violated the law and placed themselves, as well as others, in danger," said Police Commissioner William Bratton as he announced the arrests.
"Being a thrill-seeker does not give immunity from the law," Commissioner Bratton said.
Three of the men jumped from the WTC's 104th floor, while one stood watch.
Police made the arrests after a five-and-a-half month investigation that included a review of video footage, "other electronic and photographic evidence," and unspecified material collected in search warrants.
The men, all New York residents, were named as Marko Markovich, 27; Andrew Rossig, 33; Kyle Hartwell, 28; and 32-year-old James Brady.
They were released on bail.
Mr Brady was a construction worker at the WTC One, the tallest of the new skyscrapers being built at the site of the Twin Towers destroyed by the 11 September 2001 terrorist attacks.
The men face felony charges of burglary, and misdemeanor charges of reckless endangerment and jumping from a structure.
Security at the site has been in the news recently after a 16-year-old boy was arrested after he crawled through a hole in the fence and made it to the top floor on 16 March.
The teenager took a lift to the 88th floor, climbed up to the 104th floor, slipped past a sleeping security guard and spent time taking pictures.
He was later detained and faces a misdemeanour criminal trespass charge. Authorities confiscated his camera and mobile phone.
One World Trade Center is scheduled to open in early 2015.
The site includes five towers, a memorial and museum, a transportation hub, an arts centre and space for retail business.
