Koppay police excavated private land in Kokuvil, Jaffna after they allegedly received a "tip-off" that weapons belonging to the Liberation Tigers of Tamil Eelam (LTTE) were buried there.
The police obtained permission from Jaffna Magistrate Court to carry out the excavations. Despite excavating four different sites, no weapons were recovered.
Sri Lankan state forces have been accused of using weapons raids as a cover for continued repression and surveillance of the North-East.
