A 20-year-old man has been arrested in connection with the death of teenager Zoe Nelson, whose burned body was discovered in a field.
The 17-year-old was found near Branchalfield Drive in Wishaw, North Lanarkshire, on Sunday, and a murder investigation was launched.
Strathclyde Police said the suspect was in custody but gave no other details about the arrest.
Zoe was seen leaving her Newmains home at 1700 BST last Saturday.
Residents later reported seeing a fire in woods known as Monkey Hill at about 2320 BST.
Earlier this week detectives released CCTV images of the last known movements of the teenager, who was due to celebrate her 18th birthday in a few months.
The pictures were taken by security cameras in a local store at about 1730 BST on Saturday, the evening she disappeared.
Zoe's mother Marianne, stepfather Daniel, and sisters Laura Ann and Ashley said they were "shattered" by the Motherwell College student's death.
