Robbery in London - 300 deposit boxes
Discussion
GPS tracking. No cellphones allowed (on the job), surely? 
Am I being dense here but Id assumed they had stitch drilled a crawl hole. If they could open the vault door then why bother drilling? Looks like they only had limited access to boxes directly in front of their core holes. Given how easy drilling that wall is, given the minimal reinforcement, it looks like a very targeted attack on a specific box. (waits to be shot down in flames).

They got in through the drilled hole. Police picture from inside the vault is with the safe door open?IIIRestorerIII said:

looks like 300mm diameter cores, guess that's possible, given you only need width of shoulders. They wouldn't bother wasting time with the door then.Edited by stripy7 on Wednesday 22 April 13:49

drilling 2 meters of concrete with a hilti DD would make s

absolutely nuts!
I don't believe they went though 2M of wall, I think that's just press bullsh*t.t loads of noise and need loads of drill bits - especially considering they needed to create a crawl hole.absolutely nuts!
if you look at the old film from when it was opened, the wall thickness asides the door don't look anything like 2M, more like 3-4 feet.
drill wise, that's a bit drill, and apparently they had two of them, I have seen smaller ones of those go through 12" reinforced concrete including RSJ's in minutes.
Only issue I can see is they would have had to do it in at least 3 'steps'
looks like they had a 500+mm long core drill and just went through in one go (3 times)
doubt that took very long with a quality core drill cutter, maybe a couple of hours...

Am I wrong in thinking that there doesn't appear to be any rebar visible in that core - I'd have thought that the vault wall would be full of it?
There are a couple of bars visible towards the Vault interior, horizontal reinforcement would have slowed the drilling down considerably as would anything, if it caught the cutter along its length.Edited by stripy7 on Wednesday 22 April 14:54
There isn't an awful lot of steel in that concrete whichever way you look at it. I think the problem is drilling technology has moved on quite a long way since these safes were built and can be breached quite easily. Some kind of anti-drilling compound in there would be useful, some kind of fibres or mesh that would cause friction to the drill bit would be useful, it doesn't take a lot of friction to stop a core bit.

The mechanics of doing this job not that difficult.Having the guts to do it and not being to greedy is the art.They only took so many boxes.I don't condone thieving but job was professionally done.Edited by Foppo on Wednesday 22 April 19:20
Is that right what they just said on ITN news, that the boxes targeted only belong to six people?
It looks like they were after something specific? Especially if, going by the published timeline, they were gone by the Sunday morning (because after going to all that trouble why wouldn't you spend the extra time opening as many boxes as you could if you know nobody will realise until Tuesday?).
