PITTSBURGH -- Police in Braddock said a store owner fought off a robber who, a minute earlier, had borrowed money from the shopkeeper to buy potato chips.

Al Handza, owner of Al's Market, said the young man who robbed him Thursday evening is often in his store, but he doesn't know his name. Neither do police who said the man gave them an alias.

Handza said he let the man buy potato chips despite being 18 cents short, saying he could pay the difference later.

About a minute later, the man came back with a bandanna over his face and put a gun to Handza's head, according to police.

The gun fired during the struggle, wounding the unidentified suspect, who remained in a local hospital Friday.
