NYPD, Port Authority add extra security to major airports, subways around city

The NYPD added extra security around the city Tuesday after terrorists set off bombs at an airport and subway station in Brussels, Belgium. 
Subway stations were among the areas where extra security is being added. 
Police officers donned in heavy armor were seen outside the subway at East 161st Street near Yankee Stadium in the Bronx.
One Bronx man says he became a victim of the heightened anxiety when officers dressed in tactical gear allegedly threw him on the ground and searched him. Other residents say they support the increased security presence.
The NYPD said it added more officers to subway stations around the city as a precautionary measure. 
The Port Authority Police Department said it also stepped up security at its three major airports.
In addition to more police, the Port Authority said it would deploy anti-terrorism units to patrol the PATH system and World Trade Center sites. 
Mayor Bill de Blasio released a statement saying, "[The] NYPD is on increased alert across our city. While we take this threat seriously, we will not live in fear. Our lives will continue today in honor of those lost to terrorism. Securing New York City is our show of solidarity with the people of Brussels and the victims of terrorism worldwide."
