Richardson police and Breckinridge Park staff showed sketch of a man posing as a jogger who attacked a woman over the weekend to park regulars on Monday.
Richardson police stepped up patrols at a popular trail after a man attacked a woman with box cutter Saturday morning.
Police said a man posing as a jogger flagged down a female driver who was leaving a baseball tournament at Breckinridge Park.
Richardson police said they fielded dozens of phone calls Monday from people who think they may know who the man is based on a composite sketch. Police and park staff spent Monday showing the sketch to park regulars.
Police said the man asked the victim for help, saying his dog was injured and stuck in a ditch.
"Obviously, he didn't have good intentions," Sgt. Kevin Perlich said. "There was no dog in the ditch, and he physically tried to pull her down."
The woman had grabbed pepper spray before she got out of her car.
"The pepper spray was crucial in her escaping from her attacker, and the fact that she physically fought him off," Perlich said.
The woman was not seriously injured.
Police said the attacker likely experienced a reaction from the pepper spray, such as difficulty breathing, coughing or watery eyes.
