A teacher's online lesson went wrong after mistakenly sending an "indecent and disturbing video" to young children about "incest and sex" for home learning.

The teacher apologised to pupils and parents for the "genuine mistake", but mums and dads were left angry by the blunder.

Pupils aged between nine and 11 at Ings Primary School in Hull were sent a video with both incest and "vile" sexual references, Hull Live reports.

The teacher had intended to send the children a clip of famous children's author Michael Rosen performing The Car Trip for their poetry work, but accidentally sent a rude parody version.

Following complaints from angry parents, the educator, who uploaded the clip to Google Classroom to help with their home learning while schools are shut, apologised for the "genuine mistake".

The teacher apologised for the embarrassing gaffe

They said: "I am really sorry I put the wrong poetry clip on."

One dad, who asked not to be named, blasted the blundering teacher.

He said: "Teachers need to check what they're setting kids and not just being lazy and posting random links that they haven't verified.

"I half heard it the first time as I was working and she was sat next to me and was struggling to answer the questions.

"So I had to listen to the poem properly and realised something was severely wrong with what she was listening to and turned the video off.

"I ended up having to find the correct version of the poem on Google as I couldn't believe what I had heard and didn't want my daughter to listen to such filth again."

Children were left confused over the video, which also includes graphic reference to sexual acts and child abuse.

Rosen is a hugely popular children's author and poet who has written 140 books.

Kath Roe, the school's headteacher, said: "The poem was uploaded in error and we've apologised for this genuine mistake.

"We’d also like to thank the parent who got in touch with us immediately after noticing the error.

“Changes have been made to the uploading process, and we will ensure that the content shared with our students is thoroughly checked by our teachers.

“We would also like to thank parents for supporting their children in accessing online learning, and we are pleased to see that so many of our students are taking part.”
