Two Saint Lucia police officers are in Martinique for training in French military techniques.
Local reports say the two will be on the neighbouring French Caribbean Island until Friday, when they would have completed the two-week course.
The visit to Martinique forms part of the anti-crime cooperation with Saint Lucia.
Both countries are battling drug trafficking and a spike in gun violence.
According to Martinique 1 Ere, over the two weeks of intensive training, the Saint Lucian officers will undergo physical tests.
They will also engage in firearm exercises, receive training in handcuffing suspects without endangering themselves and learn techniques to control armed or unarmed individuals.
Saint Lucia and Martinique have established joint law enforcement patrols as part of their anti-crime collaboration.
They have also agreed to establish legal frameworks to advance judicial cooperation amid a violent crime surge, mainly involving firearm use, in both countries.
Law enforcers on the neighbouring Islands are concerned about the cross-border trade in illegal guns and drugs, which they say contributes to violent crimes.
In December 2022, Pierre visited Martinique for the eighth session of the Franco-Saint Lucia Joint Security Commission.
And in late January, General William Vaquette, Commander of the Martinique Gendarmerie, visited Saint Lucia as part of a delegation to talk with local officials about advancing anti-crime collaboration.
