Local police was treating the incident as a racially-motivated hoax, Dr Amandeep Singh said.
An Indian-American Sikh doctor Amandeep Singh has received death threats from an anonymous caller in the US state of Indiana. The person also sent threats to Dr Singh through text messages and claimed to have murdered the phone's previous owner, according to the US-based Sikhs Political Action Committee.
"The subject then indicated that Singh was next," said SikhsPAC, in a statement.
Investigations revealed the not only was the phone's owner was alive but the number was hacked by a third party. Dr Singh said that the local police was treating the incident as a racially-motivated hoax.
"This is one of the several similar threats against Sikhs in Indiana in the last week including one incident which involved a handgun," claimed SikhsPAC chief Gurinder Singh Khalsa.
"Intimidation and violence against the Sikh community has been on the uptick since September 11 across the country... American society has no place for this type of violence," Mr Khalsa added.
He further said that his association is working with Indiana Attorney General Curtis Hill to address several cases of harassment and intimidation against Sikhs.
Dr Amandeep Singh has been living in the United States since 2003 after graduating from a medical school in India. He is presently Chief Medical Officer at Indiana's Monroe Hospital.
Many cases of race-related crimes and threats against Indians
have been reported from the United States in the recent past.
In February, Indian engineers Srinivas Kuchibhotla and Alok Madasani
were shot at by a US navy veteran Adam Purinton, who reportedly yelled, "Get out of my country", at a Kansas city bar. Kuchibhotla died on the spot whereas Madasani was severely injured. In another incident, an Indian-origin Sikh Deep Rai
was shot outside his home in Washington by a partially-masked gunman, who screamed, "Go back to your own country".(with inputs from PTI)
