Authorities in Haiti have arrested a top official who served as general security co-ordinator when President Jovenel Moise was assassinated.

Jean Laguel Civil joins more than two dozen suspects arrested by Haiti National Police as the investigation continues into the July 7 attack at Moise’s private home.

Civil’s attorney, Reynold Georges, called his client’s arrest politically motivated.

However, it was not immediately clear if Civil had been charged with anything.

The arrest comes as more than 1,000 demonstrators gathered around one of Haiti’s most notorious gang leaders to commemorate Moise.

The crowd was mostly dressed in white as they cheered on Jimmy Cherizier, a former police officer who now leads “G9,” a federation of nine gangs that officials have blamed for a spike in violence and kidnappings in recent months.

Moise was shot several times during a July 7 attack in which his wife was seriously injured.

At least 26 people have been arrested, including 18 former Colombian soldiers.

Police are still looking for various suspects, including a former rebel leader and an ex-Haitian senator.
