Police are growing increasingly concerned for the welfare of 42-year-old Samantha Baldwin and her two children who have links to Lincolnshire.
Officers are also concerned for the welfare of her children, nine-year-old Louis Madge and six-year-old Dylan Madge who are also missing. The two boys also use the surname of Taylor. It is believed the three are together.
They were last seen near Nottingham City Centre on Monday (27 March 2017).
Lincolnshire Police said it is known they have connections in Lincolnshire and could be in the county.
Samantha is described as being 5ft 7ins tall of a slim build with shoulder length, highlighted blonde hair and green/blue eyes. She was last seen wearing a red knee-length coat from Mango but may have changed her clothing since.
Louis is described as having collar-length straight fair hair, a fair complexion and blue eyes.
Dylan is described as having collar-length straight dark brown hair, a tanned complexion and brown eyes.
Officers do not have a description of the clothing the boys were last seen wearing.
The family, who are from Newark, have connections to both Lincolnshire and Manchester and may have travelled there after they were last seen.
We ask anyone with information of their whereabouts to call Nottinghamshire Police on 101 urgently, quoting incident number 332 of 27 March 2017.
