Justin Casquejo, a 16-year-old from New Jersey, was arrested for climbing to the top of the Freedom Tower on March 16. Police believe he wore a hard hat to seem inconspicuous, creeping past sleeping security guards as he made his way to the top.
Casquejo appears to be a fan of dangerous climbs. These pictures from his Twitter were take atop a crane in Hoboken on March 14.
