Syracuse, NY -- Two more Binghamton men have been charged with assault after a Christmas brawl in the heart of downtown Syracuse left a radio host and his cousin badly injured.

Ismaeel Arif Abid Al-Ashoor and Abdul Hamid Izat Haji were charged by a grand jury, along with brothers Nouman and Hamza Khan.

The Khans were originally charged days after the Dec. 25 fight that injured radio host Joe Grosvent and his cousin James McElyea. Both victims went to Upstate University Hospital for treatment a day after the attack.

But an eyewitness provided evidence that two others in the Khans vehicle that night were involved in the attack, said prosecutor Michael Manfredi.

Al-Ashoor and Haji are accused of participating. A fifth person in the car did not get out to fight, so he was not charged, Manfredi said.

Al-Ashoor faces felony assault and Haji faces misdemeanor assault, the prosecutor said.

The Khans and the victims have provided conflicting accounts of what happened.

• Grosvent describes his version of being attacked

• Christmas night assault suspect, in his own words, says fight was self defense

But everyone agrees the confrontation started outside the Clinton Street Pub.

Later, as Grosvent and McElyea walked toward Hanover Square, they encountered the suspects' vehicle at the corner of Fayette and Salina streets.

The confrontation continued and four people jumped out of the vehicle. The fight started close to the vehicle and continued on the sidewalk nearby, the prosecutor said.

The cooperating eyewitness was on her way home after spending Christmas with family and friends. She stopped her vehicle, got out and begged the combatants to stop fighting, Manfredi said.

Meanwhile, at least two other vehicles stopped in the street to watch the fight but did not intervene, Manfredi said. Some of those witnesses may have shot video of the fight, but have not come forward.

The prosecutor called the eyewitness -- who he did not identify -- as instrumental in getting charges against all four suspects.

Nouman Khan was charged with the most serious crimes -- including gang assault -- because it was determined he caused the worst injuries to McElyea, Manfredi said. Hamza Khan faces a misdemeanor assault charge.

All four Binghamton suspects are due to court April 25. Their lawyer, Ronald Benjamin, appeared on their behalf this morning, but County Court Judge Anthony Aloi told him to bring all of his clients to court for the next appearance.
