Investigators say they have no suspects in the theft of $75,000 from an Oklahoma Wal-Mart by a man disguised as an armored truck driver.

Authorities say the suspect entered the Wal-Mart store in Bristow about 10:30 a.m. Saturday dressed similarly to a Loomis armored transport employee. The suspect strolled to the cash office, signed for the deposit and walked out of the store.

Wal-Mart employees called police after the real Loomis employee arrived about 45 minutes later. Bristow is about 35 miles southeast of Tulsa.

Bristow Police Chief Wayne Williams said Monday investigators have not identified the suspect whose image was captured by a video surveillance camera. Williams says officials don't believe the suspect lives in the area.

Williams says Wal-Mart has alerted its other stores about the theft.
