Krasner said Sabur had an old, open detainer on him from Montgomery County that must be lifted before he can be released.
Sabur, who did not testify at his trial, had been charged with aggravated and simple assault, disarming a law-enforcement officer, reckless endangerment, and resisting arrest.
Sabur was arrested Sept. 3, 2010, outside an Asian takeout at Lansdowne Avenue and Allison Street after several police officers told him and other men to clear the corner.
When Sabur objected, saying he was waiting for food, officers moved in. Videos recorded by two people with smartphones showed a developing brawl with Sabur on the ground being hit by police.
At a Municipal Court preliminary hearing in 2010, Officer Donyule Williams, an 11-year police veteran, testified that as he tried to intervene, Sabur punched him, bit him, and grabbed for the officer's pistol as they fell to the ground.
Williams' partner, Jimmy Leocal, an officer since 2000, is seen on the video hitting Sabur with an "Asp" - a telescoping baton with a ball on the end - landing several blows on Sabur's head and back.
At one point, as the crowd begins gathering and yelling at the officers to stop, Leocal is seen drawing his pistol and pointing it in the air, ordering the crowd to get back. Leocal is also seen grabbing at the cellphones of several bystanders as if to stop them from recording.
Sabur, who was originally cited by the officers for disorderly conduct, sustained a broken arm, two gashes on the back of his head, and bruises, Krasner said.
The District Attorney's Office in 2010 cleared Williams of wrongdoing but was still looking at Leocal's actions. Officials in the prosecutor's office were not immediately available to say how or if the Leocal investigation ended.
Hughes said Sabur had filed a civil lawsuit against the two officers and others that was pending in Common Pleas Court.
