Knife pulled on 70 bus going towards Market Place Drive, happened near Main St at Harris St

I saw this at approximately 10:30pm. A clearly unwell man stumbled onto the bus and sat towards the back. After seemingly sleeping for a few moments, he pulled a knife and briefly waved it when engaged (not aggressively) by a couple other passengers who boarded a few stops after him and then put it back very quickly. I reported it to the driver just before getting off at my stop a few minutes later. Already reported it to the See/Say app as well. Stay safe out there. Sorry if not the correct flair
