PORT HURON (AP) — Authorities say one man died and four other people were hurt in an accident involving several motorcycles in eastern Michigan.

The St. Clair County Sheriff’s Office said in a statement on Sunday that the man who died lost control of his motorcycle while transitioning from blacktop to gravel on Saturday afternoon.

The deceased rider is a 56-year-old man from Southgate. His name was not released. A 59-year-old female passenger was critically injured and taken to a hospital.

The sheriff’s office said nearby motorcyclists tried not to hit the first rider but also lost control of their motorcycles.
