The manager of a restaurant in Haryana's Gurugram has been arrested a day after visuals surfaced on social media showing five customers vomiting blood after consuming "mouth freshener", news agency ANI reported. All the five were hospitalised. Two of them are in a critical condition. Initial investigation found they were given dry ice as mouth freshener at Laforestta Cafe. Dry ice is the cooled and condensed form of the gas carbon dioxide, which can lead to cold burns and asphyxiation if consumed by accident.
