A top security official at One World Trade Center is resigning.
The news follow a break-in earlier this month and the arrests this week of three people who parachuted off the skyscraper in September.
Daniel Vasquez has been working as the building's assistant director of security.
Though the Port Authority owns the property and is responsible for perimeter security, Vasquez works for the Durst Organization, which began managing building security in January.
A spokesperson for the Durst Organization says that Vasquez will remain on for a transitional period.
The Port Authority is not commenting.
