A defrocked priest who was sentenced to five years in prison for sexually abusing children was arrested on a new allegation.

Defrocked priest Daniel McCormack, who has been in state custody for several years after pleading guilty to abusing several children at his West Side parish, will remain at a detention facility after being ordered held without bail Thursday on a new charge.

McCormack, 45, was wearing a gray T-shirt and long navy sweat shorts during the hearing before Judge James Brown. McCormack’s unshackled hands were clasped behind his back as Assistant State’s Attorney John Dillon detailed the latest charge of aggravated criminal sexual abuse.

Prosecutors say the newly surfaced allegation involves abuse that occurred in 2005, around the same time as other attacks he pleaded guilty to in 2007. In a separate, pending case, authorities are trying to indefinitely commit McCormack as a sexually violent person

The alleged victim, now 19, came forward late last year and told authorities McCormack fondled and abused him on two separate occasions between September and December 2005, when the boy was attending an after-school program at St. Agatha Catholic Church, Dillon said.One boy whom McCormack already pleaded guilty to abusing was in the same after-school program, Dillon said.

McCormack has been confined to a Rushville mental health and detention facility while a petition to keep him committed indefinitely to state custody under the Sexually Violent Persons Commitment Act is considered by a Cook County judge. His next hearing in that separate matter is June 12.

McCormack was paroled in 2009 to the Rushville facility after pleading guilty to three counts of aggravated criminal sexual abuse to children under the age of 13, officials said.
