On Sunday, a man walked up to the Ai-Petri. Crimea, a painting of landscapes by artist Arkhip Kuindzhi and walked off with it in front of museum patrons, according to a report in the Associated Press. On Monday, Russian police said that they had arrested a man in connection with the heist and said that they had recovered the painting at a construction site outside of Moscow. According to the AP report, the man who police have detained said that he couldn’t remember what he was doing on Sunday, but knows that he “did not commit any crimes.”

The Ai-Petri. Crimea was on display at the Tretyakov Gallery, one of the Russia’s most popular museums. The theft came just months after a man damaged a 19th century painting at the museum, sparking fears that security at the facility should be improved.

The country’s Culture Minister said in a statement to the press on Monday that museums across the country would need to boost security at state-owned museums and would consider a plan to add motion detectors to artwork to limit theft.

According to the AP, Ai-Petri. Crimea carries an estimated value of $185,000.
