Police investigating allegations of witness interference relating to a trial faced by huntsman Otis Ferry have made a fourth arrest.

A 29-year-old man, from Caynham, near Ludlow, in Shropshire, is on bail after he was arrested on suspicion of perverting the course of justice.

Ferry, son of Roxy Music singer Bryan Ferry, is on remand in prison, facing charges of assault, robbery and perverting the course of justice over an allegation that he robbed and assaulted a hunt monitor last year while riding in Gloucestershire with the Heythrop Hunt, which has its kennels in Chipping Norton.
