A Virginia sheriff's deputy died of a medical emergency after stopping a bleeding man on a moped who became combative and said, "People were after him and trying to kill him."

Sgt. Floyd H. Miles, Jr. was monitoring traffic on Sunday when around 12:30 p.m. an individual on a moped approached his vehicle, the Charles City County Sheriff’s Office said in a Facebook post. As the individual proceeded toward Miles, the moped fell onto the deputy's vehicle.

Miles noticed blood on the moped rider and asked if he was OK, according to the Facebook post. The man then repeatedly told the deputy that "people were after him and trying to kill him," the social media post continued.

Miles placed the man in the rear of his vehicle and called EMS so they could observe him further, the sheriff's office said. Once EMS arrived, they put the man in the rear of their ambulance.

After several minutes, Miles returned to the rear of the ambulance and noticed the man becoming combative toward him, according to the sheriff's office. The man struck Miles, causing a struggle to ensue between the two, the department said.

During the struggle, Miles suffered a "medical emergency," which led to him being rushed to a medical center, the sheriff's office said. He succumbed to his medical emergency, according to the Facebook post.
