Law enforcement in the Pitcairn Islands is the responsibility of the Pitcairn Islands Police, the smallest British police force, which has just two constables. In the aftermath of child sexual abuse revelations, the force did briefly number five constables including Ministry of Defence Police officers on temporary secondment. Historically, and until 2000, a Pitcairn Island resident was appointed as the island group's sole police officer, and also acted as immigration and customs officer. From 2000 to 2015, the combined police, immigration, and customs role was held by a series of foreign professionals on short-term secondment. In 2015 the Pitcairn Government website announced that both previous systems would be employed alongside each other, with one local island police officer and one foreign police officer on secondment, working together. The resident population of the islands has not exceeded 60 in recent years. There is a single police station on the main island. The legal status of officers in the Pitcairn Islands Police is established by section 79 of the Pitcairn Justice Ordinance 2000, which also defines their duties. Child sex charges A British policewoman, Gail Cox from Kent, was stationed on the island in 1999 for a short-duty secondment, but during her stay she discovered evidence of historic child sex offences. Her report led to historic sex charges, one dating back to 1972, against a number of Pitcairn Islands men, and also to a change in the way the islands of Pitcairn, Henderson, Ducie, and Oeno are policed. Ministry of Defence Police presence From the start of the investigation into child sexual abuse on Pitcairn (2000), to the conclusion of the appeals process following the Pitcairn sexual assault trial of 2004 (2006), policing was provided by the British Ministry of Defence Police, with at least two officers stationed at any time, on four-month rotation. A new prison and police station was specially constructed on Pitcairn Island, the only one of the four islands in the Pitcairn group to be inhabited. Policing since the investigation In late 2006, when the appeals process following the sex offence trials was concluded, it was announced that a retired Scottish police sergeant, Malcolm Gilbert from the Orkney Islands, had been recruited on a 12-month contract to police the island from early 2007. When Sergeant Gilbert's tour of duty ended, the British government entered into an agreement with the government of New Zealand for the island to have
