Anti-bias prof attacked

A Columbia professor who once argued for greater bias-crime protection for his fellow Sikhs was attacked by a mob of hate-filled goons who mistook him for a Muslim, called him a “terrorist” and beat him viscously, police sources said Sunday.

Prabhjot Singh, 31, an assistant professor of public affairs at the Ivy League university, had just dropped off his wife and 1-year-old son at West 110th Street near Lenox Avenue when a crowd of some 25 to 30 men started haranguing him, Singh told the post.

“Someone yelled, ‘Get Osama, get him,’ and ‘terrorist!’ ” said Singh. “Someone grabbed my beard and hit me on my chin.”

Singh ran across the street but was followed by several of the men on their bicycles who repeatedly punched him. The thugs fled up Seventh Avenue after bystanders came over to help, Singh and cops said.

He was taken to Mount Sinai Hospital, where the professor, who is also a medical doctor, works as a resident physician.

Singh last year co-authored an op-ed in The New York Times in which he called on the government to begin tracking anti-Sikh violence instead of categorizing it as instances of anti-Muslim violence.

Cops are investigating the assault as a possible bias incident, police sources said.
