A 55-year old man appeared in court on Monday charged with trying to murder his elderly father.
Alan Lockhead, whose address was given as HMP Maghaberry, has also been charged with wounding his mother.
The accused, whose solicitor stood beside him in the dock of Belfast Crown Court, was charged with attempting to murder Desmond Lockhead on March 22 this year, and of wounding Sylvia Lockhead with intent to do her grievous bodily harm
After both charges were put to Lockhead, he replied 'not guilty' to each offence.
Although no details of the charges faced by Lockhead were mentioned, a previous bail hearing was told that Lockhead is accused of trying to strangle his elderly father with a telephone cable in the couple's Belfast home, and of stabbing his mother when she tried to intervene.
Lockhead's barrister said he was awaiting medical reports, and also revealed Lockhead will be undergoing psychiatric tests ahead of the start of the trial.
While no trial date has yet been set, Judge Patricia Smyth said she hoped it would commence around next March.
Following the brief hearing, Lockhead was remanded back into custody.
