A "homophobic" video and far-right material linked to protests against LGBT relationship lessons are being investigated by police.

The clip - circulated via WhatsApp - claims primary schools are teaching Islamic children about sex and warns of a "campaign against Muslims". It has also emerged that anti-Islam material was sent to one Birmingham school at the centre of the protests. There are now fears the row is "being exploited" by two sets of extremists.

"We believe both Islamist and far-right activists are using the protests to foster division between communities," said an officer for counter-terrorist scheme Prevent, who asked to remain anonymous.

West Midlands Police said it was reviewing "a large amount" of material. No arrests have been made.

The video refers to protests against relationships and sex education (RSE) lessons held earlier this year in Birmingham where at the demonstrations' height, Anderton Park Primary School was scene to hundreds of mainly Muslim campaigners.

They said the teaching was incompatible with Islam. The social media footage was reported to police by the school's head teacher Sarah Hewitt-Clarkson, who described it as "homophobic". Read more via BBC
