A German art gallery employee snuck in his own art in hopes of a breakthrough. Now the police are involved.

A modern art museum in Germany fired one of its employees after the establishment said he was adding a personal touch to an exhibition: his own art.

According to the Munich newspaper Süddeutsche Zeitung, the self-proclaimed independent artist was a 51-year-old man who worked in the technical department of the Pinakothek der Moderne, a modern art museum that houses more than 20,000 pieces, including works by Pablo Picasso, René Magritte and Salvador Dalí – and for a short time, the employee.

The employee, who was not named in the local report, hung a painting measuring nearly 2 feet by 4 feet. A museum spokesperson told the Süddeutsche Zeitung that he did not know exactly how long the painting had been on display, but did not think it had been there for very long. The man allegedly had access to the exhibition in which his works were hung outside of opening hours.

“Supervisors notice something like this immediately,” a spokesperson told the outlet.

The makeshift addition to the gallery was dismantled and the man was fired, but police are also investigating. According to the newspaper, the employee had drilled two holes in an empty hallway to hang the painting on which the police are investigating for criminal damage to property. Citing police, the newspaper said the man had hoped that hanging the artwork would allow him to become famous.

CBS News has contacted the museum for comment.

The Pinakothek der Moderne is one of the largest museums of modern and contemporary art in Europe, housing four collections. The incident occurred just weeks after the opening of a new exhibition by performance artist FLATZ, who in 1979 “posed naked as a living dartboard”, allowing spectators to throw darts at him, and who, in the early 90s, was swinging upside down between steel plates. , hitting the metal loudly for five minutes “until he lost consciousness,” the museum said.

“The exhibition is dedicated to FLATZ’s radical concept of the body which, unmistakably, also repeatedly addresses sensitive and fragile people,” says the museum.
