The investigation by UK officers into a data breach in the Mcgrail Inquiry has been widened to include "other matters that are linked".
GBC understands matters relating to an RGP office in Secretary's Lane are being investigated.
Two officers from Northern Ireland and two from Wales are in Gibraltar.
They’re led by detective chief superintendent John McVea, who retired from the Police Service of Northern Ireland earlier this year, after a 30-year career spanning the peace process. Of those, he spent 15 years in the serious crime branch.
Speaking on GBC’s 'Gibraltar Today', the Police Commissioner Richard Ullger said Mr McVea is “totally in charge” of what he stressed was an independent and transparent investigation, with findings reported to both to the Governor and the Commissioner.
It’s a complex, sensitive situation that seems to get more complex and more sensitive as the weeks pass.
Responding to a comment by the Chief Minister about former officers who had evidence of potential criminality, Mr Ullger said he had not seen this but said if anyone in Gibraltar thinks they have any evidence of criminality they need to take it to the Royal Gibraltar Police.
He acknowledged that Ian McGrail is a “very good friend” of his, but said his profession is important to him, acknowledging he needs to be seen to undertake his role ethically without compromising his position or that of the RGP.
Answering a question from a listener, he denied there's low morale in the RGP - he said it had been affected by events, but was not low.
The Commissioner told GBC the past two to three weeks have been very difficult, he used the word “turmoil”. But despite this, he praised his officers for continuing to work hard to keep Gibraltar safe.
