GRAPEVINE, Texas (AP) _ Three cab drivers at Dallas-Fort Worth International Airport were shot today, one fatally, after a dispute with a fourth cabbie, officials said.

A 25-year-old man was declared dead at a hospital. Another man was in good condition; the condition of the third wounded person was not available.

The suspect was taken into custody by airport police, airport spokesman Joe Dealey Jr. said.

Tom Shehan, a Texas Department of Public Safety spokesman, said investigators were interviewing witnesses to find out why and how the attack occurred.

``We don't know yet what the dispute was over,'' airport spokeswoman Angel Biasatti said.

The shootings happened shortly before noon at a central taxi waiting area north of the Hyatt Regency DFW. No passengers were near the scene.
