A grandfather has been stabbed to death trying to stop an alleged domestic dispute in his neighbour's house in western Sydney.
Kima Sina, 50, died at the scene after he was stabbed a number of times in the chest at the home in Waikanda Crescent, Whalan, about 5.30pm yesterday.
"He was trying to help. Trying to help a bad situation. It was just awful," one witness told 9NEWS.
Appearing in court via videolink, Mr Krey sat with his arms folded shivering and shaking. He didn't apply for bail and is being kept under watch in a cell on his own.
The lawyer for the accused told 9NEWS his client is "finding difficult to adjust" because this is his first time in custody.
