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.
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.
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.
