Detectives have since established that the couple took a taxi from East Ham, being dropped off in Whitechapel Road at 6:14pm.

They left the taxi with an orange bag and a pram and kept their faces covered. At 6.19pm Gordon purchased a blue two-man tent, two sleeping bags and two pillows, from an Argos on Whitechapel Road.
