Tony Parris is to make fresh criticisms of the police inquiry

Tony Parris - one of the so-called Cardiff Three who were jailed and later acquitted of the killing - is expected to criticise the force's original investigation and alleged treatment of him.

It is expected he will call for a full public inquiry into the actions of South Wales Police in the original investigation.

He will tell a news conference on Monday that he is considering taking civil action against South Wales Police.

On 4 July 38-year-old security guard Jeffrey Gafoor was jailed for life for the murder of the 20-year old Ms White on Valentine's Day, 1988.

Gafoor, a security guard from Llanharan, near Bridgend, south Wales, was finally convicted with the help of new DNA evidence.

Mr Parris's news conferences comes after the Chief Constable of South Wales Police, Sir Anthony Burden, sent letters of apology earlier this week to him and four other men, who were charged with the murder following the original investigation in 1988.

Sir Anthony expressed his regret for the outcome of the investigation and for the time that three of them, - Mr Parris, Yusef Abdullahi and Steven Miller - spent in prison before their convictions were overturned.

The trio spent two years in jail before their the appeal court overturned their convictions in 1992. Two other men were cleared at the original trial in Swansea.

Sir Anthony also said a police inquiry into the original trial was under way. .

However, a legal spokesman for Tony Parris said on Saturday that he did not accept the police chief's apology and that he would give his reasons at the press conference.

South Wales Police said they could not make any comment at the moment.

Gafoor admitted the brutal murder of Ms White after he was apprehended by police using modern DNA techniques.

He had stabbed her more than 50 times in a flat above a betting shop in the Butetown area of Cardiff after changing his mind over paying her for sex.

A South Wales Police inquiry into the case will be carried out in liaison with the Crown Prosecution Service.

The investigating team will be led by Assistant Chief Constable Stephen Cahill who recently joined South Wales Police from Merseyside Police.

Mr Parris is however also calling for a separate earlier report into the original investigation to be made public.
