Thirteen suspects have been arrested in connection to the brazen heist last November of 17 Old Master paintings worth €15 million ($16 million) from Verona's Castelvecchio Museum.

Verona police worked with the branch of the Italian military police that handles cultural property to identify and apprehend 11 Moldovan and two Italian suspects.

A possible inside job, the crime took place during closing hours on November 19, 2015. Investigators allege that a museum security guard's brother was in a relationship with the sister of one of the suspects.

A museum cashier was held at gunpoint during the heist while the guard was at first said to have been made to show the thieves into the building for an hour-long ransack of the collections. The other burglars then supposedly stole the guard's keys, and took off in his car.  However, the guard has now been arrested in the case.

The missing artwork, including paintings by Tintoretto, Rubens and Bellini, has yet be recovered.
