Rotich was ambushed by 33-year-old Wallace de Sousa Nogueira, who tried to wrestle Rotich to the ground. Fortunately, police officers were following Rotich close behind on motorcycles and were able to knock Nogueira away, allowing Rotich to continue the race.
The arresting officer said that Nogueira has a history of performing acts like these in the past. Maybe someone should lock this guy up and get him some help before someone gets seriously hurt.
