SIR – May I offer sincere thanks to everyone who helped me on Wednesday, May 22. My husband, who suffers from dementia, boarded a bus to Huddersfield without me.

The staff and security at Bradford Metro, the kind lady who was able to say it was the X363, the managers and security at Huddersfield who were alerted by a man in a wheelchair, and to Bradford police who re-united us and brought us home.
