Police said Sunday that 14 people suffered carbon monoxide poisoning at an indoor barbecue in Higashi-agatsuma, Gunma Prefecture.
Emergency services arrived at the scene on Saturday afternoon to find that a group of 31 people, consisting of families whose children went to the same nursery school, had rented a holiday home and were attempting to hold a barbecue, TBS reported. Finding the weather too cold, the group said they moved several charcoal burners inside, following which 10 children and four adults began vomiting and were taken to hospital.
According to doctors, the symptoms were consistent with those caused by carbon monoxide poisoning. The group's symptoms were not serious and all were later discharged, a hospital spokesperson said Sunday.© Japan Today
