A grateful father has praised two off-duty police officers who saved his son’s life when he started choking on a chicken nugget.

Dad John and four-year-old Dexter were enjoying a meal at a beachside restaurant in Barmouth when disaster struck.

Dexter started to choke on the chicken nugget and became lifeless and floppy as it obstructed his breathing. Luckily, two off-duty police officers passing by the restaurant spotted Dexter choking and came to his rescue.
