After failing to reach a verdict over defendants accusing of having plotted the failed bombings on the London transport network in July 2005, the jury was discharged.

Monday, the same jury found four other co-defendants guilty of having planned an attack on July 21, 2005, on London’s transportation system, exactly two weeks after the suicide bombings that killed 52 passengers and injured 700 more.

Muktar Said Ibrahim, 29, Yassin Omar, 26, Ramzi Mohammed, 25, and Hussain Osman, 28, were found guilty of conspiracy to murder. According to an announcement by the Woolwich Crown Court, they will be sentenced Wednesday.

Members of the jury found in impossible to decide whether to convict Manfo Kwaku Asiedu, 34, from Ghana, and Adel Yahya, 24, originally from Ethiopia. The jury was subsequently discharged, while the two defendants await a re-trial.

Asiedu was accused of being a fifth would-be bomber who dumped his device. He said he was “duped” into getting involved.

The sixth defendant, Yahya, was accused by the prosecution of being involved in the planning. He has always denied his participation in the plotting or any knowledge of it.

The prosecution alleged Yahya was part of the “inner circle” of the group who planned the attacks and that he was “involved, at the least of it, taking part in some of the essential preparation done in furtherance of the conspiracy.”

The attempted bombings on July 21 were meant to replicate the murderous chaos of July 7, when four suicide bombers killed themselves and 52 other passengers, on three trains and one bus.

The homemade bombs failed to detonate on July 21.
