An Indian origin Sikh man came under attack while in United States.
The culprit has been sentenced to 15 months in prison.
The crime is of brutally attacking the 53-year-old in Seattle last year.
The victim has been identified as Swarn Singh, who was assaulted with a deadly weapon by Rory Benson in December 2017.
The matter was taken up by the Sikhs civil rights group The Sikh Coalition.
Swarn Singh, who maintains Sikh articles of faith including unshorn hair and a turban, had parked outside an apartment building to drop off Benson and his mother.
Rory Benson, who was sitting in the front passenger seat, attempted to suffocate him with a piece of cloth kept in the taxi to wipe the windshield, the coalition said in a statement.
He immediately ran out of the taxi, and Benson grabbed a hammer from his bag, chasing him on-foot. Benson hit Mr Singh in the head repeatedly, specifically targeting his turban and knocking it to the ground, it said.
He suffered a scalp laceration and a skull fracture as a result of the attack and was rushed to hospital. Benson was arrested.>
