New York: An elderly Sikh-American man was brutally injured and called "terrorist" and "Bin Laden" in an apparent hate crime case in Chicago, just days before the US commemorates the anniversary of the September 11 attacks.

Inderjit Singh Mukker was assaulted on Tuesday when the assailant pulled up to his car yelling racial slurs, including, "Terrorist, go back to your country, Bin Laden!" Mukker, a US citizen and father of two, was on his way to a grocery store and was repeatedly cut off by a driver.
