Formerly the deputy chief, 49 year old Gary Roberts becomes the first Island officer to take the helm.
Mr Roberts started as a constable in Douglas 28 years ago and rose through the ranks.
His predecessor Mike Langdon fostered a neighbourhood policing approach which has seen crime in the Island fall to the lowest level of any British Isles police force.
Chief Constable Roberts is committed to sustaining that policy - if funds allow:
No public board meeting for Manx Care due to General Election
But health body 'committed to openness and transparency'
Chauffeur needed to provide 'professional and discreet service' for VIPs
Opportunity to work at 'heart of Island’s constitutional and ceremonial life’
Fire officer praises 'quick-thinking' staff after blaze at fire station
Investigations continuing after incident which destroyed fire engine
Chief Minister: 'AG not out to silence debate'
