I thank the young man called Mark who came to my sister's aid when her very dear friend collapsed with a heart attack.

It was 11pm at night, she was a visitor from Canada and not at all familiar with the area in Portslade where this happened.

The lad was on his way to Tesco, stopped and gave resuscitation, called an ambulance and offered to accompany my sister to the hospital.

Unfortunately, her friend died but my sister and her friend's family would like Mark to know his help was appreciated.
