GREECE, N.Y. — An 18-year-old man is accused of stabbing a teenager during a fight on an RTS bus near the Grece Ridge Mall.

Greek police say the fight between the two bikers happened shortly before 7 p.m. on Wednesday. City resident Nahziiryahzihn Ali was charged with assault and taken to the Monroe County Jail on $5,000 cash bail.

The 15-year-old boy was taken to Strong Hospital after being stabbed in the upper body. Police say his injuries are serious, but not life-threatening.

The driver was not involved, RTS confirmed. In a statement, RTS Public Information Officer Tom Brede said:

“The RTS team works hard to provide safe, reliable, convenient and sustainable transportation to our customers every day. It is frustrating and unacceptable that someone would choose to resolve their differences through violence on the bus and disrupt people who are trying to reach important destinations in their lives. Our hearts go out to the customer who was injured and hope for a speedy recovery.

Ali was arraigned in the Municipal Court of Greece. Police released this photo of Ali:
