New surveillance footage allegedly shows Frank James on his way to the Brooklyn subway attack.

       The video, obtained by CBS News, shows Mr James wearing a high-vis vest, wheeling a cart, and carrying a bag.

       Mr James was named as a suspect in the subway attack in Sunset Park on Tuesday that left 28 people injured, including 10 with gunshot wounds.

       The gunman fired at least 33 times with a Glock 9-millimetre handgun, and police say he would have inflicted more damage if the weapon hadn’t jammed.

       A gun, magazines, gas canisters and fireworks were recovered from the scene.

       Police have offered a $50,000 reward for information leading to a conviction in the case.

       In the footage released on Wednesday, Mr James appears to be walking with a limp in the footage.

       A former neighbour who said Mr James moved into the unit next to hers in Milwaukee last year also described him as having a limp.

       The suspect in the shooting, who is still at large 30 hours after the attack, was described as a Black male with a “heavy build” standing at around 5’5” and 180lbs. He was said to have been wearing a gas mask and green “construction-style” vest over a grey hooded sweatshirt.
