A South Philadelphia soccer coach paid money to have sex with a girl on his team when she was as young as 14 and the sexual assault resulted in the birth of a child, police said.

The coach, Francisco Prado-Contreras, 39, of the 700 block of South Street in Bella Vista, has been charged with statutory sexual assault, indecent sexual assault, corruption of a minor, and related offenses, police announced Thursday.

On Tuesday, the city's Department of Human Services received a report, which it passed along to Philadelphia police, that the 7-month-old baby of a 15-year-old girl might have been fathered by the teen's former soccer coach.

In interviews, the girl told police that Prado-Contreras was a family friend and was her soccer coach in 2015. Police said Prado-Contreras was a volunteer soccer coach at the city's Capitolo Recreation Center on the 900 block of Federal Street in South Philadelphia.

The victim told police that in September 2015, she asked Prado-Contreras for a job with his house-cleaning business and one day was told to show up at an apartment building that he cleans near his home.

But instead of having her help him clean, Prado-Contreras coerced the victim into having sex with him for money, police said.

The two had sex about five times in a month and each time, Prado-Contreras gave the girl money, police said. In October 2015, the girl discovered she was pregnant, police said.

Prado-Contreras was arrested by police near his house Wednesday.

On Thursday, a spokeswoman for the mayor's office said in an email that Prado-Contreras had been barred from all city parks and recreation facilities.

"Mr. Prado has been suspended indefinitely from all PPR facilities and from participating in all PPR activities," spokeswoman Ajeenah Amir wrote of Prado-Contreras, who had been coaching for an organized athletic program affiliated with Capitolo playground,  according to the email.
