A Falmouth mum has put out a desperate plea for any information on her missing daughter.

Fourteen-year-old Crystal, also known as Mjay, has been missing from her home since Monday at 12pm.

Crystal is believed to be somewhere near Penmere Station with a friend called Conner.

Crystal is 5'5 with long wavy red hair, blue eyes and pale skin.

She was last seen wearing black jean's, blue Adidas trainers, a black shirt with a red and white check and a black hooded jacket with orange slats.
