A 21-year-old arrested in connection with the murder of soldier Lee Rigby has denied any involvement in the "atrocity".
Hayden Allen, who is reportedly a Muslim convert, was held on Saturday on suspicion of conspiracy to commit murder by detectives from Scotland Yard's Counter Terrorism Command.
Specialist firearms officers used a Taser on Allen as he was arrested in Charlton Lane, in Greenwich, south east London, some three days after the horrific killing of Drummer Rigby. He was later released on bail.
Allen said: "I had no prior knowledge of the atrocity that happened last week and I played no part in the incident or the lead-up to it whatsoever.
"My family are wholly uninvolved. I ask that the police continue to investigate and that my family be allowed without harassment to continue their lives."
Three firearms officers involved in the shooting of the men suspected of murdering soldier Lee Rigby could be back on duty within weeks.
The officers, along with two of their commanders, are currently undergoing post shooting assessments and Chief Superintendent Alistair Sutherland said he 'certainly hopes' that they will return to normal duties soon.
He said: "I will obviously speak to my counterparts in our department for professional standards and I will liaise with the IPCC (Independent Police Complaints Commission), and then I will come to a decision around putting them back to ops.
"But at this stage I would anticipate them being back on operational duty fairly quickly."
A man suspected of murdering Drummer Lee Rigby in Woolwich will be questioned by police today, a week after the soldier's death.
Michael Adebowale, 22, was shot by police after apparently charging towards armed officers in the aftermath of Drummer Rigby's death, but was moved into police custody yesterday after he was discharged from hospital.
A second murder suspect, Michael Adebolajo, 28, who was also shot by police, remains in hospital under police guard.
A 50-year-old man who was arrested in connection with the murder of Drummer Lee Rigby has been "bailed to a later date pending further enquiries", Scotland Yark said.
ITV News has obtained documents that suggest the UK Security Services were trying to recruit Michael Adebolajo and had also approached members of his family and urged them to get him to agree.
ITV News UK Editor Lucy Manning reports:
Nothing we can say can undo the events of last week.
However, as a family, we wish to share with others our horror at the senseless killing of Lee Rigby, and express our profound shame and distress that this has brought to our family.
We send our heartfelt condolence to Lee Rigby's family and loved ones.
We wish to state openly that we believe that there is no place for violence in the name of religion or politics.
We believe that all right thinking members of society share this view wherever they were born and whatever their religion and political beliefs.
– Adebolajo family statement
We wholeheartedly condemn all those who engage in acts of terror and fully reject any suggestion by them that religion or politics can justify this kind of violence.
We unreservedly put our faith in the rule of law and with others fully expect that all the perpetrators will be brought to justice under the law of the land.
And we pray for Lee Rigby's soul to rest in peace, for the Lord to comfort his parents and loved ones and provide all of us affected with the strength and fortitude to cope with this tragedy.
