STATE COLLEGE - Ex-Penn State assistant football coach Jerry Sandusky was jailed yesterday after new child-sex-abuse charges were filed against him based on the claims of two new accusers, including one who says that he screamed in vain for help while Sandusky attacked him in a basement bedroom.

The latest accusers are the ninth and 10th alleged victims described in grand-jury reports claiming that Sandusky had befriended and then molested boys he met through his Second Mile charity for troubled youth. A grand-jury document released yesterday echoed an earlier report, saying that Sandusky had given the boys gifts while also making advances on them.

One of the new accusers said that Sandusky kept him in a basement bedroom during overnight visits to Sandusky's home, forced him to perform oral sex and attempted at least 16 times to sodomize him, sometimes successfully.

"The victim testified that on at least one occasion he screamed for help, knowing that Sandusky's wife was upstairs, but no one ever came to help him," the grand-jury report said.

Sandusky now faces criminal accusations from 10 young men and more than 50 charges stemming from alleged assaults over 15 years on boys in his home, on Penn State property and elsewhere. The scandal has provoked strong criticism that Penn State officials hadn't done enough to stop the alleged assaults. The scandal prompted the ouster of Hall of Fame football coach Joe Paterno and the school's longtime president, Graham Spanier.

Sandusky, 67, has said repeatedly that he is innocent and has vowed to fight the case.

Sandusky was wide-eyed and quiet during the arraignment in a cramped district magistrate's office outside the small town of Bellefonte. He could not immediately pay $250,000 cash bail and was driven to Centre County jail by agents from the state Attorney General's Office.

He had been arrested at his home, handcuffed behind his back and driven to court wearing a blue and white Penn State wrestling jacket and matching sweatpants.

After the hearing, he avoided eye contact and did not speak with about two dozen waiting reporters and photographers before authorities placed him in the back of a silver sedan that would shuttle him to jail.

Asked what he told Sandusky during the arraignment, his attorney said he warned his client to be prepared for things to get worse.
