The Ministry of Justice is still refusing to admit any mistakes were made when a convicted murderer escaped a Kingston courtroom and manhandled a woman passer-by.

Richard Kwakye, a convicted child killer serving life, broke free from Kingston County Court on June 18, 2012 , injuring two security guards with a piece of wood with a screw fixed to the end.

He ran into St James Road outside Kingston College and pushing a 23-year-old woman off her bike before he was floored.

At the time Paul Rennie, head of custody services for Serco, said: "Following the incident we carried out a review of our prisoner escorting procedures and we are confident that they are completely safe and secure."

Her Majesty’s Courts and Tribunals Service (HMCTS), an agency of the Ministry of Justice, declined to comment.

An appeal against the decision to withhold information was made by the Surrey Comet but was rejected this week.

In its refusal notice it said: "Just to confirm HMCTS takes the issue of security within courts extremely seriously and has a robust security and safety system to protect all court users and the judiciary."

Kwakye, of Andover Road, Twickenham, was already serving a life prison sentence for the murder of toddler Siariah Letang, who died of smoke inhalation, when he attended Kingston County Court for a family matter last summer.

He received another extra three years in prison for the escape attempt.
