One of Lee Rigby's killers had 'almost no online presence at all', his brother has said in the wake of calls for tighter web surveillance.
Jeremiah Adebolajo said MI5 knew his brother Michael had 'little in the way of a digital footprint' and had no social media account or regular phone number.
Speaking in the wake of a report into what intelligence services knew about Michael, he said: "My brother was constantly and closely monitored by the security services. He had almost no online presence at all, a fact that even caused the security services to request me to keep a closer eye on him."
He called moves by the Government to expand monitoring of people's internet activities "sinister" and dismissed claims that closer monitoring of online activities would prevent 'lone wolf' attacks.
Lee Rigby's stepdad and sister criticised social media companies for failing to notify the authorities of users plotting a terror attack.
