Woolwich murder suspect Michael Adebolajo was pushed against a window by prison officers, knocking out two of his teeth, his brother has claimed.
Jeremiah Adebolajo told the BBC that he speaks to his brother almost daily and had also spoken to his lawyer and to the governor of Belmarsh Prison, where his brother is held.
Five prison officers were suspended over the incident, which occurred on Wednesday at the prison in south east London. All members "strenuously deny" any wrongdoing.
