Police reported two incidents of indecent exposure on the Schuylkill River Trail Saturday, with one suspect arrested and another on the loose.

Salin Smalley, 34, was arrested and charged after a male bicyclist reportedly spotted him around 7:30 a.m. Saturday "lying on the ground on the trail, in plain sight, with his private area exposed and partaking in a lewd act alone," according to the police report.

Police responding to the area charged Smalley, of the 1600 block of South 18th Street, with indecent exposure, open lewdness and harassment.

About 15 minutes later at 7:45 a.m., a female jogger on the river trail contacted police with reports of another man "with his pants down partaking in a lewd act alone," according to the police report.

The suspect fled up the stairs from the river trail to JFK Boulevard and remains on the loose.

Police described him as a Hispanic male, in his late 30s to early 40s, with a stocky build, black hair, wearing a grey jacket and carrying a backpack.

Sexual harassment, including assaults on female joggers, have been reported widely on the river trail, and led to calls for increased security along the Schuylkill, including increased police presence and surveillance cameras. 

Earlier this spring, Councilman Kenyatta Johnson recruited volunteers to help police the trail.
