A teenage attempted murder suspect who was mistakenly released from jail has been recaptured by police.
Jordan Francois, 18, was on remand from Wandsworth Prison in southwest London.
A £10,000 reward was being offered by the Metropolitan Police for information which led to his arrest. Scotland Yard had said he was "unlawfully at large".
Francois was known to have ties to north London, and was arrested in Edmonton at 5.35am on Saturday morning.
The Prison Service has now confirmed it will be "formally investigating" the incident.
A spokesman added: "Releases in error are a very rare but regrettable occurrence. The number of incidents have fallen significantly in recent years with figures down by a quarter compared to 2009/10 but every incident is taken extremely seriously and we are not complacent."
