Trespassers release footage from top of Shard

A group of trespassers managed to break into the Shard - western Europe's tallest building - and scale the pinnacle, it has emerged.

Photographs taken at the summit of the 1,016ft (309.7m) skyscraper have been posted on the Place Hacking blog.

The feat was apparently accomplished in December, after the group evaded security guards to mount a crane perched on top of the structure.

A spokesman for the Shard's developer said security had been tightened.
