Woolwich murder suspect Michael Adebolajo was forcefully pushed against a window by prison officers, knocking out two of his teeth, his brother has claimed in an interview with the BBC.
Jeremiah Adebolajo said he spoke to his brother on an almost daily basis.
Five staff at Belmarsh Prison have been suspended and a police investigation has begun into the incident.
But the Prison Officers Association has strenuously denied its members did anything wrong.
