Apart from the two madmen who went berserk on Wednesday afternoon, local police have arrested a man and a woman on suspicion of conspiracy to murder 25-year-old British soldier, Lee Rigby.

Although the departed member of the second battalion of the Royal Regiment of Fusiliers was not in uniform when he was attacked and killed, he was wearing a T-shirt for a British veterans' charity, according to witnesses. Police would not confirm if Mr Rigby had been a specific target or if the Wednesday afternoon hacking spree was indeed meant to terrorise UK.

The identities of all four implicated in the murder of Mr Rigby continue to be withheld until charges have been filed, as per the standard operating procedure in British enforcement laws.

However, Anjem Choudary, a former head of the radical group Al Muhajiroun had identified one of the two madmen as Michael Adebolajo, a Christian who around in 2003 converted to Islam.

What's even more ironic was that Mr Adebolajo had cropped up a number of times in "several investigations" conducted by the security service MI5 in recent years. But the UK's internal counter-intelligence and security agency didn't think he was a threat to the nation's welfare.

According to Mr Choudary, Mr Adebolajo had participated in several demonstrations organised by the group in London in recent years.

Still, the MI5 considers Mr Adebolajo and his accomplice "lone wolves," although counter-terrorism officials are working round the clock to see if they are part of a cell that has massive plans to carry out further terrorism rampage in the country.

But sources alleged that Mr Adebolajo's affiliation with the banned Al Muhajiroun group should have already placed him on MI5's "radar."

Maajid Nawaz, a former Islamist now connected with the London-based Quilliam anti-extremism think-tank in London, said that based on the rampage video, the two madmen seemed to have been inspired by Al Qaeda.

"There is always mood music playing before these attacks happen," Mr Nawaz told The Associated Press. "In this instance, I'm not saying they are operationally linked to Al Qaeda, but these men clearly felt an affinity to this global jihadist zeitgeist. And they wouldn't have had to have visited any foreign countries for this ideology to have resonated with them."
