[Updated at 12:05 p.m. ET] A district attorney in central New York says that despite credible allegations of sexual misconduct against minors, he cannot bring charges against a former Syracuse University assistant basketball coach because the statute of limitations has expired.

Onondaga County District Attorney William Fitzpatrick offered a personal apology to Bobby Davis, a former Syracuse ball boy who says he informed Syracuse police in 2002 that he was subjected to inappropriate sexual contact by Bernie Fine.

Davis, now 39, alleges the former coach touched him inappropriately beginning in 1984, before he entered seventh grade, and the abuse continued until he was 27.

Fitzpatrick said was forced to get a subpoena to compel Syracuse police to hand over records related to the case.

Mike Lang, a stepbrother of Davis, also accused Fine of inappropriately touching him at various locations, including university basketball facilities. Similar allegations made by Zach Tomaselli, 23, are still being investigated by federal authorities.

Fine has not been charged with a crime and has maintained his innocence, saying the allegations are "patently false in every aspect." Syracuse fired him last month after Davis reiterated his allegations in an interview with ESPN and Lang went public with his allegations.

The district attorney's announcement comes after federal agents searched the home and office of the former coach, looking for possible evidence of his alleged interactions with minors, according to unsealed court documents.

The investigation at Syracuse comes in the wake of a sex abuse scandal at Penn State University, in which former assistant football coach Jerry Sandusky was accused of sexually abusing boys over a span of 14 years. Sandusky has maintained his innocence throughout the investigation - saying he only "horsed around" with the disadvantaged boys in his care - and is currently free on $100,000 bail.
