No further action will be taken against six men who were arrested over the murder of soldier Lee Rigby in south-east London.
All six were arrested on suspicion of conspiracy to murder after the soldier who married in Southowram was stabbed on May 22 near his barracks in Woolwich. They were later bailed.
The men, aged between 21 and 50, were arrested between May 23 and 27.
Michael Adebolajo, 28, and Michael Adebowale, 22, have been charged with his murder. They deny the charges.
Those released without charge include a 29-year-old man arrested on May 23, and three men aged 28, 24 and 21, who were detained on May 25.
A 22-year-old arrested on May 26 and a man aged 50 was held the following day.
