A senior government official in Benin has told the BBC that the leader of Sunday's failed coup is taking refuge in neighbouring Togo.
Speaking on condition of anonymity, the official said that the government would request Lt Col Pascal Tigri's extradition. Togo's government has not yet commented.
The failed coup came after a series of military takeovers in West Africa, raising concern that democracy is increasingly under threat in the region.
It was thwarted after regional power Nigeria sent fighter jets to dislodge the mutineers from a military base and the offices of state TV following a request from President Patrice Talon's government.
A group of soldiers appeared on state TV early on Sunday to announce they had seized power, and gunfire was heard near the presidential residence.
