Sierra Leone, 2023 — military coup conspiracy

Sierra Leone (SLE)West Africa, AfricaJuly 31, 2023

Event Summary

This entry is coded 31 July 2023, corresponding to the July to August 2023 coup plot arrests in Sierra Leone under President Julius Maada Bio, an episode distinct from the later armed attack of 26 November 2023. On 31 July 2023 Sierra Leonean police issued a statement saying the security sector had been following intelligence about individuals, including senior military officers, working to undermine the peace of the state, and that several arrests had been made. Preliminary investigations indicated the suspects had planned to use purported peaceful protests scheduled for 7 to 10 August 2023 as a guise to unleash violence against state institutions.

On 8 August it was confirmed that 19 people had been arrested, including 14 serving armed forces personnel, police officers, and a retired chief superintendent extradited from Liberia, all accused of state subversion. The context was post-election tension following Bio's disputed June 2023 re-election and a regional coup wave. Critics of Bio's government concluded there was no real plot and that it was a pretext to repress the opposition, since the authorities withheld names and ranks.

The 31 July 2023 coding matches the police statement and arrests.

The government's failure to give more names or ranks of those arrested led critics of Bio's government to conclude there was no plot and that it was an excuse to repress the opposition, which had denounced irregularities in the past elections.

Editorial Note

Coded 31 Jul 2023 matches the police statement and arrests exactly; this is distinct from the separate, later 26 Nov 2023 armed attack on Freetown barracks. Verified as the July 2023 Sierra Leone coup plot, though critics called it a pretext. First Sierra Leone record in the run.

Cross-Reference

Only one dataset carries it. One of the three reference datasets we check against carries this event; the others do not list it. That is not a contradiction — the datasets cover different periods and use different thresholds — but it means the record has had less outside corroboration.
