Police are searching for three young siblings and their mother after the children were reported missing from Gloucestershire.
Officers say they are concerned for the welfare of three-year-old Pauly-Boi, five-year-old Jolene, and eight-year-old Betsy.
The children were last seen in Cheltenham at around midday on Friday.
Their current whereabouts are unknown, though police believe they are with their mother, Jessica.
Gloucestershire Constabulary say officers have conducted a number of enquiries to locate the children and their mother as there is a court order preventing them from being in the care of their parents.
Assistant Detective Inspector Faye Bennett said: “I am appealing directly to Jessica or anyone who may be with the children to make contact with us immediately.
“We want to check that the children are safe and well and would urge anyone with information to please make contact with the police.”

Pauly-Boi is described as having dark blonde hair, while Jolene is said to have mousey brown hair and Betsy has long blonde hair.
It is currently unknown what the children are wearing.
Their mother Jessica is described as being tall, of a slim build, and with a pale complexion.
Anyone who has information on their whereabouts is asked to call Gloucestershire Constabulary on 101, or 999 if the children are present at the time of the call.
