Lanarkshire police have launched an appeal for information to help trace Lauren Young and her two children, five-year-old Zak and three-year-old Mason.
They were last seen at around 3.35pm on Monday, May 10, near Livingstone Drive in the Murray area.
The Lauren, 23, is white, around 4ft 11in tall, with long black hair and blue eyes.

“Similarly, Lauren if you are reading this, let us know you, Zak and Mason are safe and well,” she added.
Anyone with information can contact police on 101, quoting incident 2961 of May 10.
