LulzSec hacker: 'Internet is a world devoid of empathy'

LulzSec gained international attention when they hacked the Sony website in 2011, taking down the company's PlayStation network for weeks and accessing millions of users' accounts. The action was estimated to have cost the company over $100m (£65m).

The hacking collective went on to wreak a trail of chaos across the web during their 50-day campaign - targeting organisations including the FBI and Britain's Serious Organised Crime Agency (SOCA).

In his first television interview, the Scottish teenager behind LulzSec's PR operation, Jake Davis, who on Wednesday was handed a 24 month sentence, talks to BBC Newsnight's Susan Watts about how he was increasingly drawn to life online.
