Buncrana based Garda chief Supt Kevin English is moving from Inishowen to Ballymote in Co. Sligo.
Letterkenny native English will be replaced by Supt Andy Archibald who is coming from the Garda Crime and Security Section.
This is the latest move in a massive shake up of the force in the County.
It is understood every district in Donegalis to see a change in its senior personnel.
The county will also see a reduction in the number of superintendants based here - from five to three.
Chief Supt. Terry McGinn has admitted the changes will ‘leave a gap’ in the force’s management structure locally.
Speaking at a meeting of the Donegal Joint Policing Committee Supt McGinn admitted that a replacement has not been found for former Buncrana chief, Supt Vincent O’Brien, who has retired,
The shake up comes against a backdrop of recently released statistics that show a drop in most types of crime in the county during the first quarter of the year However, Supt McGinn said the theft of home heating oil and copper, mostly from unoccupied buildings, remains an issue.
The number of fatal and serious road accidents increased by a third.
But all other types of crime experienced a fall with sexual offences down by 52 per cent, assault causing injury down by 55% and minor assault down by 5%.
Possession of drugs fell by 51%
Supt McGinn said the fact that people had been brought before the courts in relation to much purblised aggravated burglaries, particularly against the elderly had given assurance to people. She thanked the community for its support.
