A young man's life was saved by a humble Penguin biscuit as he began slipping into a life-threatening coma.
Student Zack Stafford, 20, had nodded off after a game of football in the park with friends following a late night out the day before.
But when best mate Tom Lynch couldn't wake him he realised something was wrong.
Tom, 21, who lives in Blaby, said: "His speech was slurred and his eyes were rolling back in his head. I poured water on his face to try to revive him.
"I know that he is diabetic and was afraid he would slip into a coma."
Tom called an ambulance before taking Zack back to his home in Glen Parva.
Then he desperately knocked on neighbours' doors to see if they had any chocolate to raise his blood sugar levels.
He said: "Eventually someone gave me a whole pile of Penguin biscuits which I fed to Zack. His mum also got him to drink orange juice.
"When the paramedics arrived they said if Zack had been left for another half-an-hour he could have slipped into a life-threatening coma.
"I am glad I woke up when I did."
The paramedics checked Zack over, giving him a clean bill of health and praising Tom's intervention.
All Zack remembers is being fed Penguin biscuits as the ambulance arrived at his home on Sunday afternoon.
He was diagnosed with type one diabetes when he was 16.
Zack said: "I owe my life to Tom. The paramedics said I could have gone into a coma if it had not been for him.
"We had been out the night before in Nottingham and decided to go for a kick about in a local park with friends. But I had not had much for breakfast.
"After the game we decided to chill out. The next I remember was lying on my couch eating chocolate and the paramedics arriving.
"I know I have to eat regularly to ensure my blood sugar levels do not drop.
"I also have to take two to three injections of insulin a day. I took my injections – but I ignored the food part.
"I think I was a bit silly. But I can't thank Tom enough."
