It is crucial - our mission can only be successful if we are working with everyone else," Sir Iqbal said. Police have tried to reassure Muslims they will crack down on those carrying out "revenge" attacks. Five people have been arrested on suspicion of attempting to petrol bomb a Sikh temple in Belvedere, south-east London.

"No-one should smear or stigmatise any community with these acts."
