The New York Police Department (NYPD) is looking for the young men responsible for hospitalizing a Muslim man in The Bronx on Friday, while civil rights group are calling for the FBI to step in and launch a hate crime probe.

The incident occurred Friday evening around 5:30 p.m. in the Parkchester neighborhood when 43-year-old Mujibur Rahman was picking up his 9-year-old niece from school, reports PIX 11. The Bangladeshi man was dressed in traditional Muslim garb when he was attacked from behind by two masked teens while his niece watched in horror.

Police say the suspects were shouting "ISIS, ISIS" as they hit, punched and kicked the man, until he fell to the ground. At one point, he became unconscious. The assailants, who are believed to be teenagers, then took off without stealing anything from Rahman.

Although Rahman's niece was not harmed during the attack, a family friend said the incident has been traumatizing.

"She could not sleep," they told NY1. "She said she didn't want to go back to school anymore."

Meanwhile, Rahman was taken to the Jacobi Hospital where he was treated for cuts, swelling and bruises on his head, face and arm. The father of three told ABC's Eyewitness News that he believes he was attacked simply due to his faith.

"I believe as a Muslim they hate us, they hate me, and that's why," he said through a translator.

"Blood was everywhere - nonstop," added the victim's brother, Mohammed.

On Sunday, the New York chapter of the Council on American-Islamic Relations (CAIR-NY) urged federal agents to investigate the case as a hate crime.

Bronx Borough President Ruben Diaz Jr. also issued a statement, saying, the "hateful attack on a Muslim individual in Parkchester is in no way representative of the shared values of the people of this borough."

He added, "An attack on one of us over race, religion, gender or sexual orientation is an attack on us all. The people of The Bronx are united in their condemnation of this abhorrent incident."
