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 has fired one of its employees after the facility said that they added a personal touch to an exhibit – their own art. 

According to Munich newspaper Süddeutsche Zeitung, the self-proclaimed freelance artist was a 51-year-old man who worked in technical service at the Pinakothek der Moderne, a modern art museum that holds 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 up a painting measuring almost 2 feet by 4 feet. A spokesperson for the museum told Süddeutsche Zeitung they weren't sure how long the painting was up, but that they don't believe it was up for very long. The man is said to have had access to the exhibit in which his art was hung outside opening hours.
