the suspect, frank james, was in court today, ordered held without bail. prosecutors argue that he should remain in federal prison in brooklyn because the attack was p premeditated, carefully planned and caused terror among the victims and the entire city. and they claim he could carry out more attacks because he had ammunition and other gun-related items in a storage unit in philadelphia. but his court-appointed defense attorney argued against a rush to judgment and said james should be credited for seeing his photo on the news and calling crime stoppers himself, telling police where they could find him. and we have learned that four of his alleged victims remain in the hospital tonight, though the most seriously injured have been released. abc's janai norman leads us off in brooklyn once again for us tonight. >> reporter: frank james appearing today before a federal judge in brooklyn, 48 hours after allegedly unleashing carnage and mayhem on a rush hour subway train. prosecutors calling the attack "entirely premeditated," and "carefully planned," saying it "caused terror among the victims and our entire city." james now represented by public defenders. >> we are all still learning about what happened on that train and we caution against a rush to judgment. what we do know is this. yesterday, mr. james saw his photograph on the news. he called crimestoppers to help. he told them where he was. >> reporter: yes, it was james himself who called in the tip that led to his own arrest. police nabbing him as he wandered around manhattan's east village, where bystanders already had a sense that they were looking at the most wanted man in new york city. >> i just saw him walking behind me and he was mumbling and saying [ bleep ] about the fbi. and literally, i was telling my wife, "i think that's him, walk faster." >> reporter: james taken into custody without incident. >> perp is in custody. >> is that the perp? >> confirmed. >> reporter: investigators have been piecing together clues, examining hours of video. abc news has learned they believe james may have rushed the attack, allegedly setting off smoke grenades earlier than he planned. they think he dropped to one knee to avoid the rising smoke and opened fire from that crouched position. they say that's why the victims were mostly shot in their hands or legs. in the chaotic aftermath, police say james slipped onto another train. this picture shows him emerging from another station. investigators were able to determine his identity from items he allegedly left at the scene -- a gun, a bright orange vest, a credit card, and the key to a u-haul rented in his name. but those things weren't discovered until after the bomb squad cleared the area. police say that gave james a head start to escape. >> the public helping out in this case. janai norman joins us now from outside federal court in brooklyn. and james had not yet entered a plea. the judge ordering him held without bail? >> reporter: yeah, linsey, prosecutors calling him a severe and ongoing threat to the community, pointing to ammunition and other gun-related items found in a philadelphia storage unit, to argue that frank james had the means to carry out more attacks. he's now being held, as you said, without bail, and though he did not enter a plea, his attorney asking the judge to provide him with psychiatric care. linsey?
