The mother of a murdered teenager has threatened legal action because her son's killer should have been wearing an electronic tag.

Helen Long said she will contact her solicitor after it emerged an error by Worthing Magistrates' Court meant Kieran Wright's tag was not replaced.

Murderer Kieran Wright, 17, was supposed to be at home when he killed his former schoolfriend Michael Morgan at a late night party.

But a mistake by Worthing Magistrates Court meant that he was not wearing a tag for two days.

The mix-up occurred after court officials sent through a notice to tag Wright with the wrong date on it.

During those two days Wright murdered 15-year-old Michael.

Today Her Majesty's Court Service apologised for its mistake.

But Mrs Long, of Nicolson Drive, Shoreham, said: "If Kieran had been tagged then my son would be alive today, it's as simple as that.

"Someone has made a massive error here and I'm going to pursue this legally.

"It is beyond belief and I feel extremely let down that when he should have been tagged and under a curfew he was roaming the streets and able to kill my son."

Wright, of Adelaide Square, Shoreham, who has a history of violence, was sentenced to life in prison last week for killing Michael on July 1.

He attacked his sleeping pal with two kitchen knives and a table leg with a screw protruding, causing 30 separate injuries to his head.

If he had been wearing the tracking device it is understood police could have been alerted that he was out between 7pm and 7am.

The company which fits the tags, Group 4 Securicor (G4S), said Wright was given the device as part of his bail conditions for a previous offence.

A spokesman said: "What has essentially happened here is that Kieran was meant to be on a tag but the court issued the wrong documentation to G4S.

"G4S cannot just go ahead and tag someone without the proper documentation, otherwise it would be in breach of its contract with the Ministry of Justice.

"Essentially, in the meantime, while the court and G4S were working together to get the right documents, the murder was carried out."

A spokesman for Her Majesty's Court Service said: "We wish to convey our deepest sympathies to the family and friends of Michael Morgan.

"This was a terrible crime and our thoughts are with them.

"Following this tragic incident we instigated an urgent investigation into the breakdown of procedures between the court concerned and G4S.

"As a result of this investigation procedures have been tightened up locally to prevent a similar event occurring."
