Her appointment was unanimously approved by the Humberside Police and Crime panel after PCC Matthew Grove, proposed her for the post.

[13] After Keith Hunter was elected as PCC in May 2016, Curran was given six months to improve the force after it was rated inadequate by Her Majesty's Inspectorate of Constabulary (HMIC).

Nine months later, after a further HMIC inspection which identified further "significant failings", Hunter asked Curran to consider her position, and she announced her retirement.

Hunter sought legal advice, and Curran was allowed to retire before the statutory procedure to remove a chief constable was started.

In June 2024, Anderson announced his intention to retire,[18] with Judi Heaton appointed as interim Chief Constable for six months the following July.

The helicopter, later codenamed Oscar 99, was equipped with a thermal image camera and conventional video camera, a radio system giving access to emergency service frequencies, and as part of its previous air ambulance use, a stretcher for hospital patient transport.

The mounted section was disbanded in July 2013 in order to save £500,000 per year amid budget cuts to the force, with the unit reported to have been deployed only 27 times during 2012.

In October 2006 it was named as the worst-performing police force in the country (jointly with Northamptonshire Police), based on data released from the Home Office[85][86] In 2007 the force moved off the bottom of the unofficial league table thanks to "major improvements" in performance, according to the Home Office.

After inspections by Her Majesty's Inspectorate of Constabulary (HMIC) between April and August 2009, their report identified Humberside Police as one of the top eight forces in the country.

He said, "The delay in processing them stops people taking up work and has a crippling impact on voluntary groups who have to get their volunteers approved.

[90] On 19 October 2015, in a report published by HMIC, Humberside Police was the only force in the country classed as inadequate.

The report suggested that the force had a "limited understanding" of demand for its services, and raised "serious concerns" over the way it was organised.

HM Inspector of Constabulary Mike Cunningham said: "Humberside Police has a limited understanding of the current and future demand for its services and, as it is unable to fully match resources to demand in some important areas, this affects its ability to provide a good service to the public."

[93] On 19 November 2015 the East Riding of Yorkshire Council agreed to reconvene a panel to review the force after October's HMIC inspection.

The panel ended up criticising both police and crime commissioner Matthew Grove and chief constable Justine Curran for refusing to attend one of its meetings.

On 6 May 2016, Labour's Keith Hunter was elected as PCC, receiving over 76,128 votes in total during the second round, compared to Grove's 51,757.

[99] Evison was re-elected to the post in 2024 with a widened margin of 4,237 votes compared to Labour candidate Simon O'Rourke.

[102] Humberside Police participated in the ITV documentary series Hotel Custody, which in three episodes, from 28 August 2022, covered the operation of the Birchen Way custody facility in Grimsby, aiming to show the facility's method of treating remanded detainees as "customers rather than criminals".
