The surveillance camera at the G & B Grocery shows a man wearing a ski mask, threatening the clerk and other people in the store, including three children. He grabs the money and is trying to run out of the store when one of the customers chases him.
KREM reports ( http://bit.ly/TZ80w4 ) it was the clerk's brother.
He tackled the fleeing man Monday going out the door. Officers arrived a few minutes later and arrested a 25-year-old man for investigation of robbery, assault and possession of a stolen firearm.
