The reward is now $15,000 for information in the search for a man who sexually assaulted a woman in the popular Knox-Henderson neighborhood earlier this month.
A friend of the woman assaulted came forward to add $5,000 to the already $10,000 reward for information leading to an arrest and indictment.
Police said the 30-year-old woman got separated from her friends after watching the Dallas Mavericks win the NBA championship at a bar on Henderson Avenue. She was attacked after leaving J. Black's to walk to her car, which was parked on Garrett Avenue.
A homeowner found her the next morning, naked and bleeding.
"Her injuries were severe -- I mean, she was beaten extremely bad," said police spokesman Senior Cpl. Kevin Janse. "It was a very violent attack, to the point where she lost consciousness and very easily could have died from this attack."
Police said the last thing the victim remembers was being punched repeatedly in the face.
Anyone with information should call Crime Stoppers at 214-373-8477.
Reducing the Risk of Sexual Assault
Valerie Gonzales, a sexual assault prevention specialist at the Dallas Area Rape Crisis Center said there is nothing a person can do to prevent a sexual assault but there are ways to reduce the risk.
The latest news from around North Texas.
"There really is something to be said for safety in numbers," Gonzales said. "When you are leaving, make sure you are leaving in a group,make sure your friends get to their car safely, and it's not just, 'Hey, see you later,' and everyone walk to their car."
She also suggested people carry their keys in their hands so they can be used as a weapon. And people shouldn't hesitate to ask for an escort to their car.
"I would hope every club and bar in Dallas would comply with that and help patrons," Gonzales said. "You should be able to ask and get escort to car."
