Police say it was shortly before 8:30 Monday night, when Abdul Cruz asked another passenger to borrow his phone to make a call.
The victim says once Cruz got the phone, he got off the bus and ran.
The victim also got off the bus and started chasing Cruz, who threatened to shoot the other man when he caught up and grabbed Cruz's shirt.
The victim called his father, who while on the way to get his son, saw Cruz on Philadelphia Pike, and called police who made the arrest.
