A newborn baby girl found with fatal injuries at a Sheffield home died as a result of stab wounds, according to South Yorkshire Police. The infant was discovered at a property on Holywell Heights in the Wincobank area on Sunday morning after officers were called due to concerns for her safety.

Despite the efforts of emergency services, the baby was pronounced dead at the scene. Police have arrested seven people, aged between 15 and 37, on suspicion of murder.

Two of the arrested individuals, aged 26 and 37, were released on bail. However, police confirmed on Tuesday that a warrant had been secured to extend the custody time for the remaining five suspects as investigations continue.

Detective Chief Inspector Tom Woodward, who is leading the investigation, acknowledged the distressing nature of the incident for the community and the emergency responders. "Everyone involved in responding to this tragedy – from the first officers and paramedics on the scene to the detectives now leading the investigation – has felt the profound impact of this investigation," he stated.

He added that the police are committed to pursuing all lines of inquiry to achieve justice for the baby. "We will confront every difficult and distressing challenge and pursue every line of inquiry with determination and care to secure justice for her," Woodward said.
