In a statement Wednesday, the U.S. Postal Inspection Service says it’ll offer up to $50,000 to information leading to an arrest and conviction of a person involved in burning the Lake Street Post Office or the Minnehaha Post Office.

The arsons occurred between May 28 and May 30, just days after Floyd was killed by Minneapolis police. Ex-office Derek Chauvin is charged with second-degree murder in Floyd’s death.

The fatal arrest sparked riots and protests in the Twin Cities. Hundreds of buildings were damaged, looted and set on fire — some were burned to the ground. Damage estimates for Minneapolis alone are believed to be upwards of $100 million.
