Police said a woman was stabbed at a Dallas Area Rapid Transit station, interrupting service for several hours Tuesday morning.
The woman was on the platform at the Pearl/Arts District station on Bryan Street when police said a man stabbed her in the face at about 5:30 a.m.
The woman lost a lot of blood, according to DART officials, and was taken to Baylor University Medical Center. Her condition is not yet known.
Police shut the station down for nearly three hours to investigate. They said they don't know why the woman was stabbed, but were reviewing surveillance video, which shows the victim and suspect getting off from different sets of doors.
DART officials kept bus shuttle service available at the Victory, West End, Deep Ellum and Cityplace stations.
As of Tuesday night, DART police were unsure if victim knew suspect.
Police have a picture of the suspect but have not released it to media. They plan to work with other police departments to find the suspect, who is believed to be 35-40 years old. He will be charged with aggravated assault with a deadly weapon once arrested.
