Dallas police are seeking the public's help in tracking down a serial rapist suspected in attacks on at least eight women in one Dallas neighborhood since June, including six in the past two weeks.

MyFoxDFW.com reported that the latest victim came forward Wednesday to report she was attacked after learning about the manhunt for the suspect in the media.

The eighth victim said she was attacked on Aug. 28 in the same area, which is near downtown Dallas and next to the southeastern edge of Fair Park, where the state fair will open later this month.

In addition to their location, the attacks share several similarities, police said in a statement. The assailant in each was a black man in his mid-20s to early 30s who was armed with a handgun. He wore shorts and a T-shirt, masked his face using various types of cloth and in some cases, had on prescription glasses. The attacker approached his victims, forced them to secluded areas nearby, and then robbed and sexually assaulted them.

"He is armed with a handgun and he demands the victims - or guides them through a demand - to a secluded area nearby where he sexually assaults them," Maj. Jeff Cotner of the Dallas Police Department told MyFoxDFW.com.

"There are no additional injuries to the victims other than the sexual assault, and then he lets them go."

The victims reported that their attacker approached them on foot, but may have driven away in either a gray four-door Honda Civic or an older-model gray four-door Volvo.

The suspect has been targeting women who are out walking in the early morning hours near the park. Police said they have stepped up patrols in the area, but that people should avoid walking near the park in the early morning hours.

MyFoxDFW.com reported that some residents have criticized authorities for waiting to send out an alert notifying residents of the attacks before a link was established.

Dallas Police Chief David Brown defended his department's actions, noting that the victims of the first two rapes were initially reluctant to share details of the attack with police.

"I've taken great pains at looking at all the things we've done looking back at the first two rapes and what we knew and what we could come forward with," Brown told the station.

Police said Wednesday they have a DNA sample from one of the attack victims and testing on it is being expedited, according to the report.
