Friends of a missing Clydebank teenager have launched an urgent plea for information leading to her whereabouts.

Schoolgirl Sarah Tyrell has not been seen since 10pm last night.

Friends have described her appearance as out of character and have appealed online for information.

Pal Millie Webster launched an online appeal and said her mum and gran are worried sick about the teen. 

She said: "Sarah was last seen late last night and hasn't been in contact since."

"Everyone that knows her including her mum and nana are absolutely worried sick!"

"Any information, even the smallest may track us to finding her and getting her home safe."

It is understood family and friends have been in contact with Police Scotland.
