Bustos told the Post that he expects to charge the suspect with aggravated assault and perhaps further charges by weeks end after he receives information that the sheriff's office has requested from Uber through a search warrant, it said.
Investigators have interviewed the driver, the suspect and another passenger who was in the car, Bustos said.
He said that the driver picked up the two passengers together in Moline, Illinois and began to drive them toward their destination. The male passenger and the driver got into an argument, he said.
The argument was about where peoples loyalties lie. There was an argument over where people were from, he said.
The Sikh Coalition said that the male passenger started asking Singh, the driver, a series of questions: What is your status here? Which country do you belong to? Do you serve your country or do you serve our country?
Singh, a legal US resident who does not speak fluent English, said he serves the United States and India, because his parents live there. Then, Singh said, the passenger put a gun to his head and said he hated turban people, the report said.
Sikh men in America, repeatedly mistaken for Muslims because of their appearance, have been the victims of numerous hate crimes including a man murdered immediately after 9/11 by an assailant who said he thought his victim was Arab, and six members of a Sikh temple in Wisconsin killed in a mass shooting.
Also, a nationwide million-dollar campaign was launched by Sikhs in the US to spread awareness and address the collective misunderstanding over the minority community amid a spike in hate crimes against them in the country.
The We are Sikhs campaign was launched by the National Sikh Campaign (NSC), a non-profit organisation.
