According to the theatre's website, the tear gas was released during a scene in which there is a confrontation between two characters (played by actors Milan Peschel and Georg Friedrich). Shots fired from a pistol were reportedly teargas cartridges instead of blanks. The audience of approximatetly 80 people dispersed and, according to the theatre, around 30 returned to the show. "So far it is unclear whether the incident was [caused by] a faulty cartridge," reads the website.
Emil und die Detektive continues in the Großes Haus (Big House) Jan. 5 and 11.
