RHI scandal: PSNI considering request for investigation after receiving letter from Ulster Unionist MLA Steve Aiken
Ulster Unionist MLA Steve Aiken has referred Northern Ireland's botched eco-energy scheme, which precipitated the current Stormont crisis, to the police.
The total Renewable Heat Incentive (RHI) spend in Northern Ireland is estimated at over £1 billion over the next 20 years.
The Treasury is set to cover £660 million of that, with Stormont landed with the remaining £490 million.
Former deputy First Minister Martin McGuinness resigned after DUP leader Arlene Foster refused to step aside while the RHI scheme - which she established in 2012 as enterprise minister - is investigated.
Some boilers are producing profits of more than 80% for users, the Stormont assembly has been told.
On Monday DUP Economy Minister Simon Hamilton told his scrutiny committee there had been a degree of "fraud" involved in the RHI scheme.
MLA Steve Aiken said on Tuesday: "I have written to the Chief Constable of the PSNI (George Hamilton) on foot of assertions made by the Minister for the Economy at yesterday's emergency economy committee meeting."
Meanwhile a DUP adviser accused by a party rebel Jonathan Bell of blocking cost controls on the RHI has said his father-in-law runs two green energy boilers under the scheme.
John Robinson, special adviser to current DUP Economy minister Simon Hamilton, insisted the poultry farmer signed up to the scheme before he married his daughter and stressed he had never advised anyone to join the botched state-subsidy initiative.
Mr Robinson, a former director of communications with the DUP, told the Press Association neither he or his wife had any direct involvement with the business or RHI.
He said his father-in-law joined the scheme before he started to work directly with Mr Hamilton.
On Monday, suspended DUP MLA Jonathan Bell used Assembly privilege to claim he was thwarted in his efforts to clamp down on the multi-million pound RHI overspend because two DUP special advisers "have such extensive interests in the poultry industry".
Mr Bell, himself a former DUP economy minister, named Mr Robinson and fellow DUP special adviser Timothy Johnston.
In response, the DUP branded Mr Bell's allegations as "outrageous, untrue and unfounded mud-slinging".
A party statement on Monday said: "Timothy Johnston has no interests whatsoever in the poultry industry and does not benefit or have any family members who applied to or benefit from RHI.
"John Robinson has no personal interest in the poultry industry. His family home farm have chicken houses but are not part of the RHI scheme and never have been recipients or applicants."
In response to specific queries from the Press Association on Tuesday, Mr Robinson said his father-in-law was part of the RHI scheme.
"I have never had any personal financial interest in the RHI scheme," he said.
"At no point have I ever advised anyone to join the scheme or sought to benefit in any way from it.
"I have two brothers who are poultry farmers. They are not part of the scheme nor did they apply to the scheme.
"My father-in-law purchased two 36KW boilers for his poultry business in May 2015, they were installed in July 2015 and he applied to the scheme on August 3 2015.
"This was before I was married in October 2015. At no time did we discuss any aspect of the scheme nor was I aware of his application to the scheme.
"Neither my wife nor I have ever had any role in the business nor have we received any benefit, financial or otherwise, from the business.
"I was appointed as an adviser in the Department for the Economy in June 2016. I was not involved in any aspect of the RHI scheme prior to taking up the post."
Mr Bell and senior DUP figures, including leader Arlene Foster, are at odds about the chain of events that led to cost controls being introduced into the widely over-budget scheme and its ultimate closure.
He was suspended from the party after making serious allegations against Mrs Foster and a number of party advisers in a TV interview before Christmas. His accusations were denied by all those he named.
The Strangford MLA's subsequent claims in an Assembly debate on Monday came at a time when Mr Hamilton is facing growing pressure to publish the names of all the beneficiaries of the RHI scheme.
Claire Hanna from the SDLP said there had been an "alphabet soup" of scandal.
"We need to start getting answers and we need people to understand that this assembly is more than a racket and a farce."
Democratic Unionist assembly member Emma Little Pengelly has hit back at her party's critics.
"I am not corrupt and I am not arrogant. I honestly know that my colleagues are not arrogant and corrupt either," she said.
"I got into politics to serve the people, to be an advocate and to deliver for the people of South Belfast and Northern Ireland."
MLA Stephen Farry said the civil service was being politicised.
He said an inquiry should examine the design of the RHI, how whistleblowers were treated and delays in taking remedial action.
"RHI has struck a chord with people because it relates to the struggles they face and can recognise incompetence at least."
Nichola Mallon, of the SDLP, said the RHI had cost the taxpayer £32 million since a whistleblower contacted the Office of the First Minister and Deputy First Minister in January last year.
A Police Service of Northern Ireland statement confirmed it had received Mr Aiken's letter and was considering the contents.
