A woman and two children who were killed in Northamptonshire have been named.
They were Anju Asok, 35, Jeeva Saju, six, and Janvi Saju, four, Northamptonshire Police said.
They were found with serious injuries at Petherton Court in Kettering on Thursday morning.
Despite the efforts of paramedics and police officers, Ms Asok, who was an NHS staff nurse, died at the scene – and the two children later in hospital.
Deborah Needham, chief executive of Kettering General Hospital, paid tribute to Ms Asok.
“She was a committed and compassionate staff nurse, who was loved and respected by her dear friends and colleagues,” she said.
“All our thoughts are with her friends and family as they come to terms with this sudden loss.”

“Forensic post-mortem examinations will be taking place today and tomorrow, and our Neighbourhood Policing Team continue to be on patrol in the Petherton Court area today to offer reassurance to local residents.”
A 52-year-old man arrested on suspicion of murder in connection with the incident remains in police custody and is being questioned by detectives.
