Scam Artists Fine-Tune their Portfolio with Armed Robbery

Police are looking for a few scam artists in Austin, Texas, who just upped the ante from theft to armed robbery.
These scam artists first talk to people very gently for giving them donation. They say it is for a charity organization. However, if the victim refuses, they pull out a gun and force them to hand over money.

Seems like they have perfected their new art!

The suspects have African accents and are working in groups of two or three.

One of the suspects is a man in his 50s in a black felt hat with a short brim and a tattoo on his left arm with the letter E or H.
