Two men arrested in connection with the Parsons Green terror attack have been released and will face no further action.
Scotland Yard confirmed that a 21-year-old man, understood to be Yahyah Farroukh, was released.
In addition, a 48-year-old man arrested in Newport, south Wales, will face no charges, the Met said.
Four people are continuing to face questioning having been arrested in connection with the terror attack on a packed Tube train.
They are a 17-year-old boy arrested in Thornton Heath, south London, an 18-year-old man arrested in Dover and two men, aged 25 and 30, arrested in Newport.
Earlier this week, Mr Farroukh’s family claimed he was innocent.
His brother Hamed said the Syrian refugee loves the UK.
He told Mail Online: ‘He is a good guy. He works in a restaurant to make a living. He would not hurt anyone.
‘My father, God bless his soul, brought us up to live decently and with high morals. Yahyah has never mingled with bad guys or militants or Daesh people.’
His sister Safa’a added: ‘Yahyah is innocent, we know he is. He could never hurt a fly. Why would he hurt the family that adopted him or the country that welcomed him?’
