Today's evidence from the inquest:
At one point an unarmed intelligence officer with the Counter Terrorism Command was about to stop Mr de Menezes on a bus to quiz him for information - but was called off when the surveillance team decided he was a suspect after all. The undercover teams at first thought the Brazilian electrician could be on-the-run terrorist Hussain Osman after he left a block of flats in Tulse Hill linked to the failed suicide bomber.
