Police investigating a burglary at a safety deposit premises in London earlier this month have released new images of the scene.
The thieves used a heavy duty drill to bore through the concrete wall of the vault, creating a hole 50cm deep, 25cm high, and 45cm wide; 89cm from the floor.
Police found the vault covered in dust and debris, and broken safety deposit boxes were scattered across the floor.
They also found several power tools, including the Hilti DD350 drill used to create the hole. An angle grinder and crowbars were also discovered.
Hatton Garden Safety Deposit Ltd shares a building with a number of other businesses.
The thieves are believed to have disabled a communal lift on the second floor of the building and used the lift shaft to access the basement, where the safety deposit firm is located.
There was no sign of forced entry to the outside of the building.
Police say the thieves forced open shutter doors into the basement and bored holes into the vault wall.
Forensic investigators have noted about 400 exhibits, including items for DNA profiling, fingerprints and other evidence.
There have been no arrests as yet in connection with the investigation.
Detective Superintendent Craig Turner, head of the investigating team, said: "We have now completed our forensic examination of the scene.
"The hours of forensic work and inquiries have been vital in order to ensure we are able to exploit all investigative opportunities to their fullest extent and assist us in identifying those individuals responsible.
"We appreciate that this situation has been frustrating for those affected by this crime and thank those individuals for their ongoing patience and support.
"Those safety deposit boxes not opened by the thieves during the burglary have been left secured as they were found throughout the examination. Owners of HGSD are in the process of making contact with owners to arrange collection of it.
"Of the 72 boxes opened during the burglary, we have only been unable to trace or contact six people who we believe have been a victim of crime. We continue to make efforts to trace them."
