While travelling in Britain you left your suitcase on a bus. Write a notice: Describe the suitcase Explain when and where

Attention! I\'ve lost my brown suitcase, small with two compartments in the bus number 14. At about 2 p.m. I was driving to the London underground station. It is very important for me, there are all my documents and part of the working material. My request is to call the telephone 543-679-001. Please. I\'ll be thankful very much. Denis.
