The first, a sexual assault, happened at Terry Hershey Park in southwest Houston.
The second was an armed robbery at Town Green Park in The Woodlands.
"I didn't have anybody to ride with today, but I'm watching and wherever I go and stop, I make sure that I paying attention to other people," bicyclist John Northorop told us Saturday at Hershey Park.
Police say a woman jogging at Hershey Park stopped at a park bathroom Friday morning. That's when two men came barged in, took her jewelry and sexually assaulted her.
According to investigators, the men were young -- one possibly a teenager -- and both got away. One suspect had on a grey sweat shirt with a Rice University emblem. The other was wearing a black jacket.
"My wife found about it yesterday," Northorop said.
Northorop says his wife usually jogs at Hershey Park, and she found out about the attack from a neighborhood alert. She skipped her jog Saturday.
Police have ramped up patrols this weekend, saying the suspects could strike again. They encourage people to exercise with a buddy.
It's the same advice park visitors at Town Green Park in The Woodlands are getting after an aggravated robbery happened -- also in broad daylight.
"The robbery concerns me. I get out about once a week. It's an even busier place in the summer," one neighbor told us.
Investigators say a man in a red hoodie pulled a gun on a park visitor, demanding his wallet and personal property. That suspect is still on the run.
