Two brothers from Upper Norwood and another man from Streatham have been convicted of being part of a terrorist gang led by a man calling himself "Osama bin London".

Yassin Mutegombwa, 22, of Upper Norwood, pleaded guilty today at Woolwich Crown Court to attending a place used for terrorist training.

The plea comes a week after another member of the gang of would-be terrorists, Kibley Da Costa, 23, of Shrubbery Road, Streatham, was found guilty of providing terrorist training, two counts of attending terrorist training and one count of possessing a record containing information likely to be useful to a terrorist.

The pair were part of a group of young men who met under the leadership of Mohammed Hamid, a man who gave his name as Osama bin London when arrested by police in Oxford Street.

The court heard Hamid organised terror training camps in Cumbria, the New Forest and paintballing in Kent.

Tipped off to the Cumbria gatherings, the Met Police's anti-terror unit sent an undercover officer to infiltrate the group.

The officer, known as Dawood, also filmed some of the group, including Kibley, rehearsing military drills and attacks on the camps.

Video footage played to the trial shows Kibley using a stick to represent a gun to train the others how to use a weapon.

Mutegombwa's guilty plea means the end of an order preventing the reporting of the conviction of his younger brother, Hassan, 20, who was found guilty in November of inviting an undercover police officer to provide money to send another person overseas for the purposes of terrorism.

The Old Bailey heard Hassan Mutegombwa, of Ravensdale Gardens, Upper Norwood, asked Dawood for £266 to help "a brother" pay for a one-way flight to Africa so that he could carry out "hidra".

Mutegombwa was carrying a one-way ticket to Nairobi, military fatigues and a hooded top with Soldier of Islam written on it in his luggage when he was stopped at Heathrow Airport on July 25, 2006.

He denied the offence, but was convicted by a majority verdict in November 2007 and sentenced to 10 years in jail.
