A manhunt is underway in Dresden following the heist.

Police received a call early Monday morning at 4:59 a.m. saying that a break-in was taking place.

The suspects were seen on CCTV, but disappeared before anyone could catch them.

"The suspects came in through a window, and walked towards a glass vitrine, smashed it and left, they disappeared," Dresden police Chief Criminal Director Volker Lange said.

The security personnel in the museum saw the two suspects on CCTV and called police, following the museum's security protocol.
