The New York Police Department says it is responding to a report of an explosion near Times Square.
The response is centered in the area of the Port Authority bus terminal.
A law enforcement source told CBS News that early reports indicate that a possible pipe bomb went off in a subway tunnel. The source said one person was in custody and an additional person was injured.
It’s led to delays along some of the subway lines that pass beneath the bus terminal.
Some passengers have been evacuated as a precaution.
A law enforcement source told CBS News senior investigative producer Pat Milton police are looking at a possible suicide bomber but the situation is fluid.
People reported seeing the bomb squad responding and posted images of the scene on social media.
