Ex-gangland enforcer, Paul Ferris, has finally settled a six-figure bill with the taxman following a lengthy probe into his earnings lasting four years.

The former criminal-turned-author revealed how investigators carefully went through his commercial affairs - including books, film deals, and his time as a security firm consultant - dating back as far as 12 years ago.

Now, though, it is understood the 53-year-old has struck an agreement with HMRC.

Speaking to The Scottish Sun, Ferris referred to the inquiry as a “financial MOT,” further insisting nothing even remotely illegal arose from it.

He told the newspaper: “What you have is government institutions which are not favourable coming in and doing their job.

“And they find out the horror story is not the horror story - it’s just, ‘Okay, you owe a few quid and you have to sort this out’.

“If you have done something wrong - like make an application for a mortgage that isn’t right - you are going to be done for fraud.”

The Crown Office said the case was now closed.

Ferris’ life was depicted in the 2013 film, The Wee Man, starring Martin Compston as a younger Ferris which tells the story of how he entered the city’s crime underworld, working his way up the ranks as an associate of Arthur ‘The Godfather’ Thompson Sr.
