Solomon Islands police have increased patrol on the border with Bougainville amid concerns of Bougainvilleans crossing illegally.
The police patrol boat, Lata, is currently in the Shortland Islands, which are very close to the south of Bougainville main island.
Deputy Police Commissioner, Gabriel Manelusi, said that the Lata is carrying specialist staff who have teamed up with local police to investigate alleged criminal activities by people crossing the Solomon Islands and Papua New Guinea border.
He said the officers wanted to ensure the Shortlands' communities are not undermined by any foreign nationals acting illegally.
