Warburg (dpa / lnw) – At a party in Warburg (Höxter district) at the weekend, 14 people were injured by irritant gas.

A police spokesman said there had previously been a physical altercation between the party guest and the two employees, and the exact course of events has yet to be determined. Due to the use of irritant gas, the air in the toilet area was so heavily polluted that 14 people were injured and had to be treated. The hall was cleared and the party ended prematurely.
