A child whose body was found at a home in Bicester on Thursday has been named by police.
Sarah Dahane, aged 20 months, was identified by her father this morning.
The child’s body was discovered by police yesterday morning after a relative raised fears over her welfare.
Det Ch Insp Ian Hunter said: “Whilst the circumstances of Sarah’s death remain unexplained, we are carrying out a detailed and thorough investigation to establish exactly how and why she died.
“We are supporting Sarah’s father, who is separated from her mother, with dedicated family liaison officers.
“From information available to us at this time, it would appear Sarah’s mother has left the UK at some stage during Wednesday evening.
“She is believed to have travelled to Kenya. Her exact whereabouts are unknown and we are working with other authorities to establish her exact location.
“While we are working with those individuals and authorities that were in contact with both Sarah and her mother prior to her death, we urgently wish to speak to Sarah’s mother to better understand exactly what has happened.
“We strongly urge her to present herself to the authorities.”
More tests and toxicology examinations are due to take place to identify the cause of the child’s death.
Supt Colin Paine, commander of the Cherwell and West Oxon police area, said: “Incidents such as these are very sad, but isolated and rare.
“We continue to have neighbourhood patrols in the area addressing any community concerns.”
A scene watch will remain in place in Herald Way until late tonight as examinations at the house continue, police said.
