A New York subway attack, an unbroken vehicle, fugitive attacker

A number of people have been injured and unbroken devices have been found on the Brooklyn subway in New York.

U.S. media report that a broad investigation is under way after shooting at Sunset Park Station, while people are being asked to avoid that part, writes NBCNew York.

According to reports, up until now five people were reportedly injured by a person who had a gas mask attached and an orange construction vest, who fled the site without being caught.

Some sources quoting American media say the attacker may have thrown a device before opening fire at this station.

The victim's rate of injury is not yet known correctly.
