SEATTLE - A woman was stabbed and another woman beaten when a traffic dispute set off an early morning brawl involving about 40 people in a downtown Seattle parking lot.

Seattle Police Department spokeswoman Renee Witt says the melee was "like a free for all," according to a report in the Seattle Post-Intelligencer.

Witt says the brawl was reported about 2:10 a.m. on Saturday. She says patrol officers, a SWAT unit and the department's Gang Unit responded to melee at the Bank of America Plaza in the 800 block of Fifth Avenue.

A woman in her 20s suffered a deep knife wound in her abdomen and was rushed to the Harborview Medical Center. Witt says the wound was not considered life-threatening.

Witt says medics treated a woman who was beaten and stomped on by a man during the fight. That woman was not hospitalized.

The stomping victim and other witnesses told police two people became angry because they believed the two women, both in the same car, had cut in front of them in a parking garage.

A Seattle man who was described as in his 20s was booked into the King County Jail for investigation of assault.
