Nancy Kerrigan’s brother just pled not guilty to charges of assaulting their father Daniel–who died yesterday after a struggle at the family’s Massachusetts home.

Mark Kerrigan cried during his arraignment in Woburn District Court–where he faced one charge of assault and battery on an elder with serious bodily injury.

According to the police report, Daniel collapsed after Mark allegedly choked him during an altercation that erupted over the use of a telephone. Nancy’s mother said Daniel suffered a heart attack during the altercation.

Mark’s bail was set at $10,000..

Court officials in Woburn, Massachusetts tell TMZ Mark–who faces one charge of assault and battery on an elder with serious bodily injury–was released from the local detention center after posting his $10,000 bail.

Mark will now be allowed to live at his mother’s house–under house arrest–and must wear a GPS device and submit to drug and alcohol testing.

Mark’s father, Daniel, died shortly after their alleged altercation on January 24.

The Medical Examiner ruled Daniel’s death a homicide — and determined he died from cardiac dysrhythmia after suffering a neck injury during the alleged physical altercation at his house.

A rep for the family said they were “delighted” to have Mark back home.

Nancy Kerrigan is no stranger to harrowing headlines. In 1994, a hit man hired by the husband of rival skater Tonya Harding kneecapped her with a collapsible baton at a figure-skating practice.

Harding became notorious in conjunction with the January 6, 1994 attack on her competitor Nancy Kerrigan. The widely publicized attack took place during a practice session for the 1994 U.S. Figure Skating Championships in Detroit. Harding’s ex-husband, Jeff Gillooly, and her bodyguard, Shawn Eckardt, hired Shane Stant to strike Kerrigan on the knee, though Stant actually struck Kerrigan’s thigh a few inches above the knee. Harding won that event, while Kerrigan’s injury forced her withdrawal. After Harding admitted to helping to cover up the attack, the USFSA and United States Olympic Committee initiated proceedings to remove her from the 1994 Olympic team, but Harding retained her place after threatening legal action. She finished eighth, while Kerrigan, who recovered from her injuries, finished second.
