Two London men admitted plotting an al-Qaeda inspired bomb attack on the London Stock Exchange, today.

“Lynchpin” Mohammed Chowdhury, 21, and his London accomplice Shah Rahman, 28, were among four conspirators involved in the plot who pleaded guilty at Woolwich Crown Court, where they were set to stand trial.

Chowdhury, of Stanliff House, Tower Hamlets and Shah Rahman, 28, of St Bernard’s Road in Newham, admitted preparing for acts of terrorism by planning to plant an improvised explosive device (IED) in the toilets of the London Stock Exchange.

Chowdhury and Rahman were followed by undercover detectives on November 28, 2010, observing Big Ben, Westminster Abbey, the London Eye and the Palace of Westminster.

Prosecutor Andrew Edis QC: “Mr Edis said that the four involved in the Stock Exchange plot had not intended to maim and kill.

“Their intention was to cause terror and economic harm and disruption. But their chosen method meant there was a risk people would be maimed or killed.”

Five more men pleaded guilty to other terrorism charges.
