Investigation following the art theft at the Kunsthal gallery in Rotterdam has shown that the suspects entered through a door at the back of the building. They seized and made off with the paintings in a very short space of time. The collection and examination of camera footage is now in full swing, as is the rest of the criminal investigation. So far no images have been found which are suitable for publication.

Burglars stole seven art works from the Kunsthal at Westzeedijk in the course of the night between Monday and Tuesday. They forced their way into the building at about quarter past three in the morning and were outside again very soon after.

The alarm went off at the security company, whereupon police and security personnel launched an investigation. There were no visible signs of forced entry outside the premises. Nor was anyone present inside the building.

Security personnel only discovered the paintings were gone after they went inside the building.

Forensic detectives made a thorough investigation, carefully securing any clues and evidence both inside the Kunsthal and in the immediate vicinity. They were able to establish how the perpetrators gained access to the building without leaving any sign of forced entry.

The Kunsthal contacted the owner of the works in question. On Tuesday morning the Kunsthal submitted an official report to the police as soon as it was ascertained for certain which paintings were involved. The publication of images attracted world-wide attention to the robbery and the stolen paintings. An international alert was also issued for the pictures.

Apart from images from inside the Kunsthal itself, camera images of the immediate vicinity were also secured. All images are being studied carefully by the detectives. So far no camera images suitable for publication have been found.

The Dutch television programme 'Opsporing Verzocht' also drew attention to the case on Tuesday evening. Images of the stolen paintings were shown during the programme.

Thanks to all the media attention, dozens of tips were received and are being investigated for their usability.
