Two 19-year-old men arrested in connection with the murder of skydiver Stephen Hilder have been released on police bail pending further inquiries.
The men were arrested by Humberside Police on Wednesday. A force spokesman said both men have now been released from custody.
Mr Hilder died on July 4th at Hibaldstow airfield, in North Lincolnshire when he fell 13,000ft to his death.
Detective Superintendent Colin Andrews, who is leading the murder investigation, said: "We are in consultation with the Crown Prosecution Service and a file of evidence will be sent to them for consideration.
"The investigation into Stephen's death does remain ongoing and officers are continuing inquiries. I'm still very keen to speak to people about Stephen's death and urge anyone who knows anything about the circumstances surrounding the events of Friday July 4 to contact me.
"It is our belief that somebody out there knows exactly what happened to Stephen and that person must now come forward. I remain confident this case will be solved and the person or people responsible will be brought to justice."
Mr Hilder, who was a veteran of dozens of parachute jumps, had been taking part in the National Championships of the British Collegiate Parachute Association when he died.
