On June 7th, the bodies of two sisters Nicole Smallman, 27 and Bibaa Henry, 46, were discovered in a park in Wembley. Police believe the pair were killed by a stranger.

Since then, there have been questions over the police's response to the case.

Two officers were suspended amid allegations they took selfies next to their bodies.

The murdered women's mother - Mina Smallman - says the behaviour of officers involved in the case shows that there is still institutionalised racism in the Metropolitan Police.

She spoke to the 大象传媒's Martin Bashir.
