High Court action is being taken today against two men - including a man from Sunderland - over information posted on Facebook and Twitter in relation to the identity of James' Bulger's killers.
Images recently appeared on Twitter claiming to show an adult Venables, who was released from jail on licence with a new identity in 2001.
Publication of any image or information that leads to the identification of Venables or Thompson is prohibited, under the protection of a court order.
Jon Venables and Robert Thompson were jailed for life after they abducted and murdered two-year-old James in Liverpool in February 1993.
Neil Harkins and Dean Liddle, who is from Sunderland, are accused of breaching the injunction that stops identification of James Bulger's killers.
