A man who was riding the Metrobús on Monday afternoon is now fighting for his life after being stabbed to rob him, according to police. The bus was traveling on the H12 route near Iverson Street and 23rd Parkway in Prince George’s County. Police confirmed that the man was taken to the hospital with life-threatening injuries. Metro Transit Police are working to investigate and identify any suspects. Last month, another attack on a Metrobús involved individuals who threw a woman out of the vehicle. The incident occurred on the M4 bus heading to the Deanwood area of northeast DC.
