Police say around 2:30 a.m. Saturday, a man approached a woman as she was walking in the 3300 block of Fairmount Street, covered her mouth, dragged her toward the creek in that area and sexually assaulted her.
The suspect then fled on foot toward Turtle Creek Boulevard.
People who frequent the area were surprised to hear about the attack. They said it is common for people to walk home from nearby bars after hours.
The assault does serve as a grim reminder about the hazards present in any part of town.
"It's not the first time that something like this has happened, so I'm always on guard. I know there've been some instances on the trail where women have been taken advantage of, but this really hits close to home," said Carly Matthews, who lives nearby.
Some apartment buildings in the area are sending out notices for residents to be on alert. Police said they have increased patrols.
The suspect is described as being Hispanic, between 20 and 30 years old and having a thin build and a mustache. He was wearing jeans and a tan polo shirt.
Detectives would like to speak with anyone who was in the area during the time of the attack who may have seen the suspect or who might have additional information that could help in the case. They are encouraged to call 214-373-TIPS (8477).
Crime Stoppers is offering a reward of up to $5,000 for information that leads to an arrest and indictment in this case.
