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:
Man who launched attack on van driver sentenced
34-year-old handed 18 month suspended sentence
RNLI's last serving Mersey class boat visits the Island
12-20 Leonard Kent to be retired
