The father of of missing RAF gunner Corrie McKeague has said he believes "several" people are perverting the course of justice in relation to his son's disappearance, after police made an arrest.

A 26-year-old was last night being questioned by detectives after being arrested on suspicion of perverting the course of justice. It is the first arrest in the baffling case.

Mr McKeague, 23, whose girlfriend, April Oliver, 21, is expecting their first baby, disappeared after going out with friends on September 24.

He became separated while leaving the Flex nightclub in Bury St Edmunds and may have tried to walk the 10 miles back to his base at RAF Honington.
