Detectives investigating the death of Argentine footballer Emiliano Sala have arrested a man on suspicion of manslaughter by an unlawful act.
Mr Sala, 28, had just signed for Cardiff City when a plane carrying him crashed into the English Channel north of Guernsey on 21 January.
His body was brought to Portland Port in Dorset in February, with police investigating the circumstances of his death.
Detective Inspector Simon Huxter, of Dorset Police, said: "We have carried out a wide-ranging investigation into the circumstances of the death of Mr Sala and continue to work with partner agencies including the Civil Aviation Authority.
"As part of this investigation we have to consider whether there is any evidence of any suspected criminality and as a result of our inquiries we have today, Wednesday 19 June, arrested a 64-year-old man from the North Yorkshire area on suspicion of manslaughter by an unlawful act.
Police said the man has been been released from custody under investigation.
Family liaison officers have been updating the families of Mr Sala and David Ibbotson, the pilot of the plane that lost contact with Air Traffic Control north of Guernsey.
The body of Mr Ibbotson, 59, from Crowle, Lincolnshire, who was flying the plane from Nantes in France to Cardiff on 21 January, has not yet been located.
Det Insp Huxter added: "This matter therefore is still subject to a live investigation and I would ask the media and members of the public to refrain from speculation, as this could cause additional distress to the families involved as well as potentially hinder the investigation.
Earlier this month, Wiltshire Police said two people would face charges over a photograph showing Mr Sala at the Holly Tree Lodge mortuary in Bournemouth.
Sherry Bray, 48, has been summonsed for three counts of computer misuse, perverting the court of justice and sending an indecent/offensive message.
Christopher Ashford, 62, has been summonsed in relation to six counts of computer misuse.
The pair, who were arrested in February, will appear before Swindon Magistrates' Court on 10 July.
