NORTH TEXAS (CBSDFW.COM) – Four North Texas police departments are trying to track down a potential serial suspect who has assaulted and groped several women joggers on multiple occasions.

Police departments from Arlington, Haltom City, Euless and Hurst are seeking the public’s help in identifying the suspect, but so far, the descriptions police have of the young man are vague.

In all the cases, the women were jogging alone in well-trafficked area when the man comes up behind them and starts groping their breasts and genitals over their clothes.

In one case in Hurst, the man managed to get the woman down the ground and sexually assaulted her with his hands.

Police say they need to get him off the streets before he rapes someone.

“Not to mention just what you have to go through when you’re violated like that,” said Arlington Police Lt. Christopher Cook. “You want to be able to jog, you’re out there your exercising. A lot of these women had air buds in. They’re listening to their music and so it’s a very scary ordeal.”

Arlington investigators believe the first incident happened Friday August 17 in the 3800 block of Perkins Road around 5:00 p.m.

A woman was jogging when the young man approached her from behind and grabbed her wrist and assaulted her by touching her.

The second incident in Arlington happened Saturday, August 25 in the 3800 block of Morris Drive around 8:00 a.m.

The suspect approached a woman from behind while she was jogging and assaulted her through touching her.

The third incident in Arlington happened Saturday, September 1 in the 4000 block of Perkins Road around 6:30 a.m. It was reported that the suspect approached a woman from behind and assaulted her through touching and pushing the victim onto the ground before running off.

In each of these incidents, the victims were not injured after the assault occurred and the suspect ran away.

Police don’t have a sketch of this man, but the victim’s are all reporting he’s a young black man, possibly his early 20s.

He’s about 5’8” to 5’10″.

Police in Arlington say they have stepped patrols in parks and trails.

Anyone with any information that can help identify this suspect is asked to contact Arlington Detective Jenkins at 817-459-5305 or Tarrant County Crime Stoppers at 817-469-TIPS.
