Found hand bag with insulated lunch bag inside on bus #21 at about 5:25 pm today (8/31/2017). I think it was left by a person that got off at the stop before Morgan st. stop. I heard someone bang on the side of the bus after it took off but did not actually see the person. I got off the bus on Morgan and walked back to other stop but could not find anyone waiting. Describe the bag and I will figure out how to get it back to you.
