The people of Northampton want to know what has happened to their missing millions.
The borough council loaned £10.25m to Northampton Town Football Club to redevelop the stadium and nearby land, but the funds have seemingly vanished, leaving an unfinished stand and the football club almost going under.
This story began in 2012 when a decision was made to invest in the new stand.
Now a police inquiry is under way into "allegations of theft and fraud, bribery, misconduct in public office and electoral offences".
In September 2017 it was announced seven people have been arrested and a further nine questioned under caution.
The following December the BBC revealed a further seven people had been questioned under caution, with money laundering added to the list of suspected offences.
Now police say case files have been prepared in relation to 30 suspects.
A five year BBC investigation has traced where most of the loan money seems to have gone, uncovering allegations millions of pounds was misappropriated by the developer appointed to oversee the project.
So far the BBC has discovered £37k in secret payments in to Mr Mackintosh's electoral fund from the company into which the bulk of the missing money disappeared.
These hidden donations are now the part of the police inquiry.
That firm, 1st Land Ltd, also received VAT repayments totalling almost a million pounds. Mr Grossman says the payments were 'entirely legitimate'.
Mr Mackintosh was also provided with free legal assistance by 1st Land's lawyer just months after money from the firm was channelled into his election campaign fund.
We established how 1st Land's funds were used to pay for tickets and hospitality for a Premier League football club.
The BBC also revealed how a senior council officer who would have blocked a loan wasn't told about the plans. The go-ahead to lend the money was given just weeks after she left.
Mr Mackintosh, who stood down as an MP ahead of the 2017 General Election, said he welcomed both police investigations and that he "will co-operate fully".
In March 2018, the BBC disclosed that Mr Mackintosh had been interviewed by police while under caution.
