After less than a year in the job, Foyle PSNI top cop, Garry Eaton is stepping down as Chief Inspector but isn't leaving the district.
Instead he will take up a new post as Crime Manager while his replacement will be Inspector Jon Burrows who steps into the position on Monday.
While he was District Commander of Foyle for under 12 months, CI Eaton does have over 25 years experience as a detective with the Metropolitan Police Service in London and the PSNI's Major Investigation Team.
In his new role he will be responsible for managing CID and public protection teams across G District which covers Londonderry, Strabane, Limavady and Magherafelt council areas.
Mr Burrows will be treading on familiar ground when he takes up his post.
He previously served as Acting Chief Inspector before Mr Eaton's appointment and during his time defended the publication of pictures of young people suspected of anti-social behaviour in the controversial Operation Exposure.
He also launched a campaign called Operation Silent Guardian which encouraged members of the public to pass information on to the police about suspected drug dealers.
Chief Inspector Eaton said: “I thoroughly enjoyed my posting as Area Commander in Foyle.
“We have had many successes over the past year and I want to thank my officers and staff for their hard work and commitment.
“I am confident that they will show the same level of support for my successor.
“I look forward to my new role and to investigating serious crime across the district.”
Inspector Burrows added: “I will try my best to continue to build on the excellent work and partnerships which already exist.
“I am deeply committed to serving the people of Derry and to making our communities safer for everyone.”
