The probe into the alleged fraudulent takeover of Rangers will take detectives “wherever they need to go”, police said today.

They are trying to track down Rangers’ former commercial director Imran Ahmad as part of the investigation into the takeover by former chief executive Charles Green in 2012.

A spokeswoman for Police Scotland said this morning: “The inquiry is ongoing and it will take officers wherever they need to go.”

Charles Green, former Rangers owner Craig Whyte, David Whitehouse and Paul Clark, who both worked for the club's administrators Duff and Phelps, are all facing charges connected to the takeover.

Whyte took control of Rangers in May 2011 but by the summer of 2012 Green had taken charge at the Ibrox club by purchasing Rangers' assets and business after it went into administration and liquidation earlier that year. He stepped down as chief executive in 2013.
