A Sikh student in California, U.S., was not allowed to board a bus after the driver objected to his wearing a ceremonial knife (or kirpan) and called the police.

Harsimran Singh, a student of the University of California in Davis, said he has travelled for the last two years with the kirpan in full view and did not face any issues until Saturday morning. “They do not say anything. They always wish me safe travels, and they continue on with their business; they did not see me as a potential threat,” Mr. Singh was quoted as saying by CBS news on Wednesday.
