A police sergeant fatally shot a man during a traffic stop in the Bronx on Thursday, officials said, the second deadly shooting by the New York police this week and the third time in three days that an officer fired at a suspect.

The shooting happened about 3 p.m. near Woodlawn Cemetery after the sergeant and two officers in a marked car pulled over an S.U.V. because the driver was not wearing a seatbelt, the police said.

The officers determined that the driver, whose name was not released, had three outstanding warrants for failing to pay fines for violations, including one for littering, the police said.

The officers told the driver they were arresting him as a result of the warrants, and he got out of the S.U.V., the police said.
