(CNN) — A 29 year-old man is suing Penn State University, its former assistant football coach and a charity the coach founded after Jerry Sandusky allegedly sexually abused him more than 100 times, according to his attorney Jeff Anderson.

The lawsuit is the first in a scandal involving the university’s former defensive coordinator, who has been accused in a grand jury report of sexual abuse against eight boys over 15 years.

The alleged abuse of the man, identified as “John Doe A,” was not disclosed in the grand jury report, said Anderson, and indicates the alleged victim was 10-years-old when he first met Sandusky.

Attorneys Anderson and Marci Hamilton said the former coach also threatened to harm the victim and his family if he alerted anyone of the alleged abuse, which occurred between 1992 and 1996.

The filing says Sandusky provided Joe Doe A with “gifts, travel, and privileges” while he attended The Second Mile camp, a nonprofit organization Sandusky founded for underprivileged children.

The lawsuit targets that organization, Sandusky and Penn State University, pointing to what it describes as an “institutional concealment” and “institutional failure” which allowed the former coach to “thrive and prosper.”

Sandusky allegedly molested multiple victims dating back to the 1970s, according to the lawsuit.

Anderson told reporters Wednesday that the alleged victim has come forward in an effort to protect other potential victims.

“I never told anybody what he did to me over 100 times, at all kinds of places, until the newspapers” reported the alleged abuse, Anderson quoted the alleged victim as saying in a written statement.

“I am hurting and have been for a long time,” he said.

Sandusky, meanwhile, has maintained his innocence. His attorney, Joe Amendola, said Monday that he is working with a private investigator in his quest to prove his innocence.

Sandusky, 67, is free on $100,000 bail. He is charged with 40 counts related to the alleged sexual abuse. He allegedly met the victims through The Second Mile.

Penn State, meanwhile, is expected hold a town hall forum Wednesday where students can ask questions about the child sex scandal that has shaken the campus.

University President Rodney Erickson and several campus student organizations will host the event Wednesday night.

“We all have questions,” representatives of three campus groups wrote in a statement about the forum. ” President Erickson is committed to making this healing process a community effort. As the University moves forward, there is a critical need for the student body and administration to have a dialogue about our plan for the future.”

Sandusky, the longtime Nittany Lions’ defensive coordinator, told NBC’s Bob Costas that he has been falsely accused and that he only “horsed around” with kids in showers after workouts. Amendola also says Sandusky is innocent.

Penn State Athletic Director Tim Curley, 57, and the school’s vice president for finance and business, Gary Schultz, 62, were each charged with one count of felony perjury and one count of failure to report abuse allegations about Sandusky. Their preliminary court hearing is set for December 16 at the Dauphin County Courthouse in Harrisburg.

In addition, Penn State President Graham Spanier and iconic head football coach Joe Paterno lost their jobs soon after Sandusky’s arrest, following criticism that the football program and university in general did not adequately handle the matter when allegations arose years earlier.

Several other people also have come forward, saying they too were sexually abused by Sandusky.
