Man in coma and eight others hospitalised after liquid nitrogen poured into pool during party
A 21-year-old man is in a coma and eight others were hospitalised after party organisers poured barrels of liquid nitrogen into a pool in León in the Mexican state of Guanajuato.

Partygoers filmed the moment four large buckets of the liquid were tipped into a pool, sending toxic plumes of smoke into the air and leaving guests gasping for breath.
The extremely cold liquid became toxic when mixed with the chlorine in the outdoor pool, causing swimmers to pass out. Victims were pulled to safety by paramedics but one man, Jose Ignacio Lopez del Toro, remains comatose.

The eight others hospitalised have since been released but some were diagnosed with cardiovascular problems. Around 200 young guests had been invited to the event hosted by German liquor brand Jagermeister.
