The suspects in the Boston marathon bombing were on their way to New York to carry out another attack, according to police.
The two men planned on using a pressure-cooker explosive, like the ones used in Boston, and five pipe bombs.
“He (Dzhokhar Tsarnaev) told the FBI apparently that he and his older brother intended to drive to New York and detonate additional explosives in Times Square,” said New York Mayor Michael Bloomberg.
Dzhokhar Tsarnaev, 19, has now been charged and could face the death penalty. He remains in a Boston hospital.
Tsarnaev is said to have told police that the additional devices were in the car he and his brother stole last Thursday night and the plan to go to New York failed after his brother Tamerlan, 26, was killed in a shootout with the police.
Dzhokhar Tsarnaev was captured the following night.
Three people were killed and 264 people were injured by the two devices planted near the finish line at Boston’s marathon on April 15.
Pakistani immigrant Faisal Shahzad was jailed for life after planting a bomb in New York’s Times Square that failed to detonate in 2010.
