Liberia's former speaker of parliament has been charged with arson over a fire which destroyed the nation's House of Representatives, local police have said.

The huge blaze broke out last December, a day after plans to remove Jonathan Fonati Koffa from his role as speaker sparked protests in the capital, Monrovia.

Koffa had been locked in a stand-off with his political opponents, with dozens of lawmakers voting for his impeachment in October over accusations of poor governance, corruption and conflicts of interest.

Koffa has previously denied any connection to the fire breaking out.

Police said on Friday that there were "credible links" to suggest Koffa was "strategically involved" in the incident. Five other lawmakers have also been detained in connection to the case.
