SANDUSKY -- A former nurse accused of abusing patients at a northern Ohio nursing home is now facing more charges.

Investigators say John Riems has been charged with 12 counts of rape and two counts of sexual penetration.

The Sandusky man already had pleaded not guilty to charges of rape, sexual battery and patient abuse.

Riems has been in jail since he was arrested in January and charged with sexually abusing a 55-year-old man and another man in his 80s.

He told investigators after his arrest that he abused almost 100 patients since the 1980s.

His attorney said Tuesday that the confession to police was false and coerced.
