Police were called to the home on Lisnahull Road around 11 a.m. on Saturday, August 29, where they found the deceased man, a seriously injured child, and a woman with non-life-threatening injuries. The woman has since been released from the hospital.

The child was transported to the Royal Belfast Hospital for Sick Children and remains in critical condition. The cause of the man's death has not yet been officially determined, and post-mortem examinations are pending.

A man apprehended at the scene on suspicion of murder and attempted murder is currently in custody. The Police Service of Northern Ireland stated that they do not believe there is any wider threat to the public and are not seeking anyone else in connection with the death.

The residence was cordoned off by authorities, with police presence in the area. A child's trampoline was visible in the back garden, surrounded by police tape. Local councilor Deirdre Varsani described the incident as a potentially serious domestic incident and urged the community to be respectful and to provide any information to the police.
