A 16-year-old youth was shot by police who mistook his water pistol for a real weapon, with one of the officers firing all 16 rounds in his gun.
Michael Jones was in critical condition Monday after being shot seven times early Sunday while riding his bicycle.
Police were looking for the youth after an off-duty police officer reported he was pointing a gun at people and cars.
Police said the youth refused to drop his toy, which looked like a submachine gun. But Jermain Congress, who was riding his bicycle with Michael, said Michael was dropping his pistol when he was shot.
Officer David Gross fired all 16 rounds from his 9mm service revolver at Jones. Sgt. Michael Jacobellis fired once.
Police Commissioner Howard Safir said a preliminary investigation indicates the officers acted properly.
"Certainly at 2:30 in the morning, it would not be unreasonable to believe this was a real weapon," Safir said, holding up Jones' black toy gun and a 9mm MP5 submachine gun.
