A 45-year-old Missouri biker was reportedly killed by two other men when he tried to stop them from attacking a woman by the side of the road.

Rodney Wood was riding his motorcycle when he saw a woman being attacked, a family friend told the Hannibal Courier-Post. He pulled over to try to help, the paper reported.

But when Wood tried to intervene, the unidentified attackers apparently turned on him and killed him, according to the Courier-Post. Wood's body was found early Sunday morning in Hannibal, Mo.

The suspects, who are 21 and 22, were arrested Sunday.

Police have released few other details about the incident.
