Unidentified robbers stole several paintings from the National Gallery early on Monday including an early work by Pablo Picasso entitled ‘Head of a Woman,’ according to the Athens News Agency.
According to Skai, another painting removed from the gallery was a work by the Dutch painter Piet Mondrian. The robbers are believed to have taken a total of four works of art from the premises.
It remained unclear how the intruders, who remained at large early Monday, gained access to the gallery as there was no sign of a forced entry, according to police.
Officers believe the robbers may have used a side entrance or window to access the premises. They were examining fingerprints found on a window sill close to the gallery’s side entrance.
The gallery features mostly 19th and 20th century Greek paintings and some choice European works. The Picasso painting is believed to have been a gift to the museum.
