Bearing the slogan, 'Enough is Enough', a group of mainly women set off at 1pm from Barn Hill, Wembley today, to march the 10 miles to New Scotland Yard, to demand an end to the police racism and misogyny that so impacted on family and friends of Bibaa Henry and Nicole Smallman.
Mina Smallman, the women's mother, was unable to take part but sent a message of support.
Marchers were asked to set their mobile phone timers for 16 hours so that their alarms would go off after the march was over, demonstrating how long it took the police to act on reports of the women's disappearance.
The Raised Voices choir sang as people assembled on Barn Hill and the music loved by Nicole and Bibaa accompanied the marchers.
The Women's Equality Party who organised the march said that this was just the beginning of the campaign for justice.
