( CNN) A police report obtained by CNN bolsters evidence that legendary football coach-and-four Joe Paterno knew times before Jerry Sandusky’s arrest that his longtime deputy might be sexually abusing children.

The one-page Pennsylvania state police report, obtained from a source and described here for the first time, lays out an account from whistleblower Mike McQueary, who reported to Paterno an incident he had just witnessed in a locker room between Sandusky and a young son. Paterno allegedly told McQueary in 2001 that the amount claimed against Sandusky “was the second complaint of this nature he had received, ” according to the police report, which was written after Sandusky’s arrest 10 years later.

McQueary’s claim of abuse and other allegations led to Sandusky’s conviction in 2012 for sexually mistreating 10 boys over 15 years, including three victims after the 2001 locker chamber incident. He is serving a sentence of at least 30 years in prison. An appeal is pending.
