Two good Samaritans jumped into action after witnessing a 70-year-old man get knocked to the ground in an attempted robbery inside a Tucson fast-food restaurant. Instead of freezing up and standing still, the two witnesses jumped in and stopped the suspect from stealing the elderly man's backpack after knocking his walker to the ground. Officers were able to quickly locate and arrest the 34-year-old suspect within minutes, charging him with attempted robbery. The victim was treated for his injuries at the scene, and police say the quick actions of bystanders played a key role in stopping the crime.
