Lawyers for Boy B, convicted of Ana Kriegel's murder, say his family has been forced to go into hiding after he was identified online.
Facebook and Twitter have been ordered to take down any material that might identify the two boys convicted of the murder.
Counsel for Boy A has handed screenshots of tweets and Facebook comments into the Central Criminal Court, which they say identify him and were taken as late as this morning.
A lawyer for an unnamed school has also told the court it has found material online which is directed at it regarding the case.
Following concerns raised by Boy B’s lawyers that material identifying him was being posted and shared online, Mr Justice Michael White ordered representatives from Facebook and Twitter to appear before his court this morning.
