Boston bombs: Dzhokhar Tsarnaev moved from hospital to prison Dzhokhar was moved hours after Michael Bloomberg, the mayor of New York, said the brothers planned to travel to New York and mount a second attack with six more bombs. The younger Tsarnaev is understood to have disclosed that he and his brother intended to attack Times Square, one of the busiest areas of the city, before he was apprehended. He told the FBI, apparently, that he and his brother had intended to drive to New York and detonate additional explosives in Times Square. They had built these explosives and we know they had the capacity to carry out the catastrophe," Mr Bloomberg said. Mr Kelly said at Thursday's press conference that Dzhokhar told investigators that he and his brother had initially planned to escape to New York to "party," but had "spontaneously" decided instead to mount a second attack. The Daily Telegraph has obtained an undated photograph of Dzhokhar in Times Square with a group of friends, one of whom was arrested by police in New Bedford, Massachusetts, following the capture of the bombers last week. An undated image recovered from a social networking site, where it was posted on April 18, 2012, shows Boston marathon bombs suspect Dzhokhar Tsarnaev (second from right) in Times Square with unidentified friends who have not been linked to alleged plans for an attack on New York
