A Chinese tourist and his teenage son have gone missing after visiting Edinburgh Castle.

Lifang Lin, 39, and his son Zixuan Lin, 13, were last seen at the landmark at around 1.45pm on Saturday, January 21.

The Chinese nationals are understood to have been visiting Edinburgh on holiday.

They speak little to no English and concerns are growing for their welfare.

Lifang was last seen wearing a red coat. Zixuan was last seen wearing a yellow coat and was carrying a blue backpack.

Anyone who may have information about their whereabouts is asked to contact police on 101.
