A Montgomery County park reopened Wednesday morning after a gunman sexually assaulted a woman the day before.
The 19-year-old woman was running in Norristown Farm Park in Norristown, Pennsylvania around 10:50 a.m. Tuesday when she was approached from behind by an unidentified man armed with a gun. He then sexually assaulted the woman before fleeing the scene, police said.
The woman was taken to Einstein Medical Center and later released.
Norristown Farm Park is a popular area where groups often hold 5K runs, parents bring their children and walkers, and joggers and bicyclists go to exercise.
"It's certainly not a place where these sorts of things happen," said Pat McLaughlin, who lives near the park. "I've never heard of anything bad here."
The park reopened at daybreak Wednesday as the search for the suspect continued.
The suspect is described as a man wearing a black mask and a dark hooded sweatshirt armed with a handgun.
