A Chicago man is facing a felony charge after allegedly riding a CTA Green Line train while carrying a machete.
Williams was accompanied by seven other male teens, ages 16 and 17, who police said went to the Beaches Branch Library "to protest and antagonize the opposing political side."
Investigators say the stabbing was the result of an apparent turf dispute between people selling items in the Times Square area, and multiple people were taken into custody.
Some were hacked to death with machetes while others died when their dormitories were set on fire, said military spokesman Felix Kulayigye.
Pictures from court documents show an employee reportedly jamming a foot inside a revolving door to keep Delaney from getting inside.
The suspect told police he shouted "Allahu Akbar" before attacking the NYPD officers with a knife, sources said.
