THE mum of murdered toddler James Bulger has demanded video website YouTube remove a sick clip mocking her sons killing.

Hundreds of other users are backing Denise Fergus, 37 who also wants the warped person responsible banned from posting future footage.

Disgusted ... Denise Fergus

But YouTube has failed to remove the clip. Denise said: This video makes me sick to my stomach to see the murder of my beautiful son being made the subject of a sick joke.

James was murdered in 1993 by youths Robert Thompson and Jon Venables.

The 1min 28sec video, entitled Hey Robert, is by poowizard1 and has him singing from the perspective of Venables, accompanied by images of the three children.

Lyrics include: Hey Robert, theres a game that we can play. Lets get a toddler and steal it from its mum.

Denise, of Kirkby, Merseyside, added: Its disgusting.

"It should be taken down immediately.

Around 230 YouTube users have also commented.

One, Toribum24, said: The only reason you have put so much effort into this video is to hurt the family of a dead child.
