A Sikh man who was jailed after being falsely accused of making a bomb threat on a Greyhound bus traveling through Amarillo in February is now speaking out, alleging racial profiling and requesting criminal charges be filed.

A New York-based civil-rights group sent a complaint to Potter County prosecutors and the county sheriff on behalf of the man, Daljeet Singh, 30.

The 10-page document demands that criminal charges be brought against one bus passenger who allegedly reported the threat and two others who restrained Singh.

Singh and Mohammed Chotri, a Pakistani man, were sitting together aboard a bus en route to Indianapolis when a passenger reportedly heard one of the men say the word "bomb."

The passenger notified the bus driver, who called 911 and pulled over on the side of Interstate 40, authorities said. Potter County sheriff's deputies arrested both Singh and Chotri and booked them into Potter County jail on charges of making a terroristic threat.

Singh wore a beard and a traditional Sikh turban at the time of the incident. In a statement, Singh said he had been speaking Punjabi while on the bus.

Both men were later cleared of all wrongdoing and released.

"The only crime I committed was wearing a turban, having a beard and speaking in a different language to another brown man on a bus," Singh said in a statement.

Since the Sept. 11 terror attacks, Sikhs in the United States have often become victims of harassment or violence by people who mistakenly associate their appearance with Islamic terrorists.

The complaint, filed by The Sikh Coalition, identifies the passenger who alerted the driver as Tianna Lynn Decamp and claims she committed the crime of false alarm or report.

"Ms. Decamp viciously profiled Mr. Singh," the coalition's complaint reads. It also says Decamp described Singh to authorities as an "Arabic male" who was "acting weird" and supposedly speaking Arabic.

The complaint also casts doubt upon Decamp's claim that she heard either of the men say "bomb."

Although there were about 40 passengers on the bus, according to the document, Decamp was the only passenger to report the purported statement.

The civil-rights group further argues that two other passengers, Anthony Lamar Lillie and Kelly Michael Morris, unlawfully restrained Singh until sheriff's deputies arrived.

Potter County Attorney Scott Brumley said Wednesday he had received the complaint and planned to review it to determine if any charges would be filed.

The Potter County Attorney's Office is responsible for prosecuting misdemeanor cases in the county.
