Urgent Matter database tracks global art crimes

The global art world is facing a growing wave of crime-related incidents ranging from museum heists at the likes of the Louvre Museum and forged masterpieces to fraud, money-laundering and vandalism of public art.

Although precise figures remain elusive, since many crimes go unreported, the FBI estimates that $4 billion to $6 billion of art is stolen each year worldwide.

Meanwhile, the database maintained by Interpol now lists almost 57,000 stolen works of art, with a significant portion never recovered.

This tracker brings together confirmed cases of theft, forgery, vandalism, fraud and institutional breaches affecting the art world. Each entry links to our original reporting and will be updated as the cases evolve.

Violent Crime

2024 Murder of Brent Sikkema

Date: January 15, 2024

What Happened: A federal judge has set a May 11, 2026 jury trial for Daniel Sikkema, who is charged in an alleged murder-for-hire plot that prosecutors say led to the January 2024 stabbing death of prominent gallerist Brent Sikkema in Rio de Janeiro. Daniel Sikkema faces life in prison on charges including racketeering murder-for-hire, conspiracy to commit murder overseas, and passport fraud, though prosecutors have said they will not seek the death penalty. He has pleaded not guilty and is being held in pretrial detention. Court records obtained by Urgent Matter detail prosecutors’ claims that Sikkema orchestrated the killing remotely through intermediaries and covert communications, while Brazilian authorities continue to pursue proceedings against the alleged hitman, Alejandro Triana Prevez.

Interpol later added the jewels to its Stolen Works of Art database. Paris prosecutor Laure Beccuau announced that four people have now been arrested while a fifth suspect remains missing.

Italy Raids Mafia-Linked Grave Robbers
