Mr Harrison was in a team of four motorbike outriders escorting the Duchess and her convoy away from an event at the Foreign Office.

Over the weekend she was moved to Tonka by motorbike and shot at the town's Independence Square while her brother was in the crowd, AFP reports.

The killer came by night – a masked man on a motorbike who struck without warning and then sped away.

Authorities in Ghana are searching for the shooter - one of a group of six suspects who they say were at the scene and fled on motorbikes.

They are a man suspected of being one of the two who waited with getaway motorbikes on the street outside the Louvre; and his wife, who faces a possible charge of conspiracy.
