French police said Tuesday they arrested a renown international jewelry thief known as “the Sultan” who stole diamonds and luxury watches from Monaco to Hong Kong, the Associated Press reported.

Jean Herrina, a 45-year-old Frenchman, was nabbed in Paris late Monday on the orders of a judge in the Riviera city of Nice, police said.

Herrina would pose as a wealthy Saudi prince and ask jewelry store owners worldwide to show him their finest pieces before slipping away with them in a moment of inattention, earning himself the nickname of “the Sultan.”

Herrina is a suspect in the theft last month of a diamond worth 150,000 euros ($147,000) from a jewelry shop in the chic Riviera resort of Saint-Jean-Cap-Ferrat.

He was previously arrested in 1999 in connection with thefts committed in Switzerland and Germany, police said.
