Two maintenance workers came to the aid of a woman who was sexually assaulted in the city's Spring Garden section Thursday night.
The men were in the area of 16th and Callowhill streets near Philadelphia Community College just before 7 p.m. when they tell NBC10 they saw a woman being choked and pushed up against a fence.
"He got her by the neck and tried to touch her private parts," said witness Ricardo Garcia.
Unsure at first about what was going on, the men watched the suspect push the victim into nearby bushes.
"He took her hand and walked her across the street and pushed her into some pine bushes," Garcia said.
That's when they called police and followed the man until officers arrived.
The man was taken into custody, but has not yet been charged.
The victim was a woman in her 20s, according to authorities. She was taken to Hahnemann Hospital where she was examined.
The other witness, Cecil Vergara, says the street was busy at the time of the assault and that he and his friend were surprised that no one else tried to help the woman.
"They were walking by and didn't do anything. Cars were going by, blowing their horns, but they didn't do anything.
