Group who got into BBC have done the same at Facebook

They climbed over a gate before walking around the London office in areas which are normally open to staff only.

During the video Trikkstar zooms in on desks at main reception where staff are seemingly unaware of him and a friend.

At the end of the clip he claims security "tried to catch us" and that they were followed outside.

The clip seemingly shows them deciding to leave before they're noticed and also sees them claiming to "eat and drink a lot" when they were in the building "because everything's free here".
