Dzhokhar and Tamerlan Tsarnaev told hostage car driver they planned to go to New York next

Dzhokhar and Tamerlan Tsarnaev told a man whose Mercedes SUV they hijacked on Thursday night that they planned to go to New York, it has emerged.

Tamerlan Tsarnaev, 26, and his younger brother Dzhokhar, 19, seized a Mercedes-Benz SUV and held the driver hostage as they sought to flee from police late on Thursday.

The Boston Marathon bombers  told the driver that they planned to head to New York, a senior official revealed, but it is not clear if they told the man what they intended to do there, the New York Times reported.

The latest detail emerged as police confirmed Dzhokhar and Tamerlan Tsarnaev likely planned more attacks, and suggests they could have wrought even greater devastation on the US after being undetected by the FBI.

Boston police commissioner, Edward Davis, said on Sunday that police believed they had planned more attacks beyond the bombings at the marathon finish line.
