Austin police have charged a man after they say he threatened several people including children with a knife on a Capitol Metro Bus.
On June 24, police say 57-year-old Purvis Lewis was aboard the CapMetro bus on route 10, standing near the front when he began yelling and cursing.
A witness told police, Lewis appear to be yelling at two children who were sitting with their mother behind the bus driver.
Police say Lewis removed a knife from his pocket and began making stabbing motions towards the children.
A passenger on the bus told police that the mother looked scared and put her arm around the children pulling them closer to her. He then stood between Lewis to protect the children. Lewis then began yelling and pointing the knife at the man.
The passenger pulled out pepper spray and told Lewis that he was going to spray him. He also told the bus driver that Lewis had a knife.
The bus driver stopped at the bus at 9th and Congress Ave, where Lewis exited.
The man rode the bus one stop further north, where he exited and called police. After calling authorities, Lewis approached the man once again with his knife, yelling at him across the street.
Police arrived and detained Lewis. They seized a black and silver folding knife from Lewis' pocket.
Lewis has been charged with aggravated assault.
