Britain's Attorney General is to pursue people who posted pictures online, reportedly showing Jamie Bulger's killers as they look today.
Anyone who shared the images could face contempt of court proceedings, because of an historical worldwide order against identifying John Venables and Robert Thompson, who were boys themselves when they killed the toddler in Liverpool in 1993.
The photos have been available online for at least the last 10 days.
Media journalist with The Guardian Lisa O'Carroll said identifying the men could jeopardise their security, and that there was also the possibility that the wrong people had been pictured.
"The order imposed 20 years ago covers anything that would lead anybody to identify the new identities of these two boys, so you can’t even name the site these photographs appeared on," she said.
"I'm sure what the police will now do is try to find out from online companies the identities (of the people who posted the pictures), and arrest them."
