NORTH TONAWANDA, N.Y. (AP) — Fire officials are investigating after a blaze damaged the western New York apartment of a volunteer firefighter who said he received a racist, threatening letter earlier this week.

Firefighters were called Wednesday afternoon to the North Tonawanda home of 28-year-old Kenneth Walker. Nobody was home at the time.

On Tuesday, Walker showed Buffalo media an anonymous letter he said was left in his mailbox on Monday. It told him to resign because he’s black.

City police, federal prosecutors in Buffalo and the FBI are reviewing the letter.

Contact information for Walker wasn’t available. He told WGRZ-TV he has never had any issues with co-workers or the public in two years as a firefighter. He said the letter made him fear for the safety of his wife and two young children.
