Following several incidents of mischievous break-ins at the World Trade Center, U.S. Senator Chuck Schumer asked federal officials to perform a review of the security at the nation's tallest building, SeattlePi.com reported.
Schumer, a Democrat from New York, said on Sunday that the Department of Homeland Security should test the building's security equipment, search for potential entry points, and monitor the performance of guards.
Joseph Dunne, security chief at the Port Authority of New York and New Jersey -- which owns the site -- said officials have already "taken significant steps to address" the concerns.
Within the past few weeks, there have been multiple instances involving daredevil stunts at the tower -- prompting a serious concern among residents and national authorities.
Two weeks ago, a 16-year-old boy was arrested for trespassing onto the rooftop of the World Trade Center.
Joe Pentangelo, a spokesman for the Port Authority, said the boy was charged with misdemeanor criminal trespass.
According to Pentangelo, the boy got into the site through a 1-foot opening in a fence and entered the building by climbing the scaffolding. The guard of the 104th floor did not see him, and he has since been fired.
On Monday, four men were arrested for performing a base jump stunt from the tower's rooftop in September.
NYPD Commissioner William Bratton issued a statement detailing the arrests of James Brady, Kyle Hartwell, Marko Markovich, and Andrew Rossig -- all charged with burglary, reckless endangerment, and jumping from a structure.
"These men violated the law and placed themselves, as well as others, in danger," Bratton said. "These arrests should send a message to anyone thinking about misusing a landmark this way."
On Tuesday -- just one day after the stunt group's arrest -- two CNN producers were arrested for trying to break into the World Trade Center to test security.
