There are new concerns on the Katy Trail after an attempted assault on a young woman Sunday morning.
Anna Chrysikopoulos, who is training for a marathon, runs the trail a few times a week. Chrysikopoulos said that as she ran the trail Sunday, a man grabbed her from behind and tried to pull her off the trail.
She said, the man "wrapped one of his arms, like he's trying to grab my hip and pull me backwards, and then he didn't really get a good grip and I was screaming, and he ran off."
A fellow runner stopped to make sure she was fine, still Chrysikopoulos was shaken up.
"I think he was trying to grab me, take me," she said.
Chrysikopoulos describes the man as, "wearing long sleeve blue button down collared shirt with pin stripes, and dark blue jeans."
Chrysikopoulos said it looked like the man had been out the night before.
"I couldnt breathe after it happened, I got really short of breath, I just wanted to take off and start running home," Chrysikopoulos said.
Friends of the Katy Trail, the group which maintains the trail, believes this to be an isolated incident and does have patrols during the weekends on the trail.
Other runners said they'll do more to try to be more aware while jogging, no matter what time of day.
"I’m running, very carefree. I’ve got my music on. I don’t even think about it. I probably should. It’s going to make me think twice for sure,” said runner Aimee Miller.
“I use it in the morning, usually when there’s a lot of people. I’m surprised it was in the morning. It’s scary,” said runner Sarah Little.
The Dallas Police Department is investigating the incident. There have been no arrests in connection with the assault.
