TULSA, Oklahoma - Police are looking for a man who robbed a Tulsa convenience store clerk late Wednesday.

A clerk told police she was counting money at the Phillips 66 convenience store at 31st and Yale just before midnight, when a man appeared and pointed something at the back of her head.

After she gave him the cash, the man got into a small, older-model white pickup which headed east on the Broken Arrow Expressway.

Police said the clerk was not injured. The clerk wasn't able to give police a detailed description of the robber.
