Former Penn State assistant football coach Jerry Sandusky sexually abused a young boy more than 100 times after meeting him through The Second Mile charity he founded in 1977, according to a civil lawsuit filed Wednesday.

The 27-page lawsuit, which was filed in Philadelphia, identifies the alleged victim -- now 29 -- as John Doe. It lists Sandusky, The Second Mile and Penn State as defendants, claiming Sandusky abused the boy at his State College home, at Penn State facilities and on at least one bowl game trip.

In a statement provided by his attorneys, the unidentified 29-year-old man said he filed the lawsuit because he did not want "other kids to be hurt and abused" by Sandusky.

"I never told anybody what he did to me over 100 times at all kinds of places until the newspapers reported that he had abused other kids and the people at Penn State and Second Mile didn’t do the things they should have to protect me and the other kids," the statement read. "I am hurting and have been for a long time because of what happened, but feel now even more tormented that I have learned of so many other kids. Now that I have told and done something about it, I am feeling better and going to get help and work with the police. I want other people who have been hurt to know they can come forward and get help and help protect others in the future.

The alleged abuse occurred after Sandusky met the then-10-year-old boy through his charity in 1992 and continued until 1996, according to the lawsuit. Attorney Jeffrey Anderson said Sandusky threatened the boy's family to keep quiet about the encounters.

"Sandusky made a threat to him that nobody would believe him and made a threat to his family," Anderson said.

"The sexual abuse occurred on multiple occasions and at multiple locations within Pennsylvania and outside of Pennsylvania; in the facilities of Penn State, particularly the football coach's locker room," the lawsuit reads. "His molestation was enabled by the negligent oversight of Sandusky by Second Mile and Penn State."

Sandusky allegedly abused eight boys throughout a 15-year period. This latest alleged victim is not among those identified in a grand jury report released this month. The former one-time heir apparent to former Penn State head coach Joe Paterno has since acknowledged showering with young boys but denied molesting them.

Sandusky's attorney Joe Amendola told FoxNews.com that Sandusky "denies the allegations contained in the civil suit filed today in Philadelphia."

"Penn State and Second Mile each had a duty to protect the minor Plaintiff when he was entrusted to their care by Plaintiff's parents," the lawsuit read. "Plaintiff's care, welfare, and/or physical custody was temporarily entrusted to Penn State and Second Mile when Plaintiff attended functions sponsored by Penn State and Second Mile, and when on properties and premises operated by Penn State and Second Mile, and when traveling with Sandusky to football activities, including a Bowl game."

Anderson said Sandusky, who remains free on bail, "belongs behind bars" today.

"Sandusky is out there free on bail or low on bail and walking the streets knowing what we know, he is out there," he said. "Imagine how the survivors are feeling,"

Anderson said the victims are afraid that Sandusky could be currently preying on children while free.

Nils Frederiksen, a spokesman for the Pennsylvania attorney general, declined comment on the new accusations to FoxNews.com due to the "ongoing nature" of the grand jury investigation.

The growing sex abuse scandal has rocked Penn State, resulting in the departures of school President Graham Spanier and Paterno. Athletic Director Tim Curley has also been placed on administrative leave, and Vice President Gary Schultz has stepped down.

Schultz and Curley have been charged with lying to the grand jury and failure to report to police. Both maintain their innocence.

In a statement to FoxNews.com, officials at The Second Mile said the organization will review the lawsuit.

"The Second Mile will adhere to its legal responsibilities throughout this process," the statement read. "As always, our thoughts and prayers are with the victims and their families."

Lisa Powers, a Penn State spokeswoman, said the university had not yet received a copy of the lawsuit.

"As with any litigation, we are unable to comment on specifics related to the case," she said.
