BARTLESVILLE, Okla. (AP) - Officials are offering a $3,500 reward for information about a robbery at the Woolaroc gift shop in northeastern Oklahoma.

Officials say a man robbed the gift shop shortly before closing Sunday night. Authorities say the robber fled with $4,500 in cash.

Woolaroc is a ranch, museum and wildlife preserve in the Osage Hills of northeastern Oklahoma. Its name is derived from three words - woods, lakes and rocks. The site is known for its Wonderland of Lights display each December.

Anyone with information is asked to call Bartlesville police.
