Police arrest a woman after the body of a four-year-old boy is found on the NSW Central Coast. According to reports, officers find the boy with significant injuries to his arms when they respond to a welfare concern. The discovery prompts an investigation, and a woman is later arrested in connection with the incident. Multiple outlets describe the boy’s condition consistently, saying the injuries are significant and are located on his arms. The articles also agree that the arrest follows the welfare response and the subsequent discovery of the body. While details about the woman’s identity, charges, and the circumstances leading to the welfare call are not provided in the excerpts, all sources indicate that police treat the case as serious and linked to the injuries found on the child. The reports present the same core timeline: a welfare concern leads to police attending the scene, the boy is found dead with arm injuries, and a woman is arrested afterward as part of the investigation.
