I saw another one where somebody sent arab andy a clip of the n-word being repeated over and over 50 times while he is on the bus. A very liberal looking white guy in his 40s threatened to stab andy so he got off the bus immediately.
Ive seen that clip. The guy was either super unstable or just trying to "out crazy" the streamer and scare him away.
You are being far too charitable with him. He essentially committed assault by creating the impression that andy was not physically safe and that he may use a knife against him.
