The body of Leicestershire Police Assistant Chief Constable Gordon Fraser has been found on a railway line in Gloucestershire after being hit by a train.
Mr Fraser had been suspended by the force over allegations of gross misconduct and fraud.
The discovery was made after officers were called to reports of a man being struck by a train in Aston Magna, Moreton in Marsh, Gloucestershire, yesterday afternoon.
Mr Fraser was pronounced dead at the scene.
The death is not currently being treated as suspicious.
A spokeswoman for British Transport Police (BTP) said the incident was reported at 12.20pm.
She said officers were investigating the circumstances surrounding the incident, and were preparing a file for the coroner.
In a joint statement, Leicestershire Police Authority and Leicestershire Police said they were "deeply shocked and saddened" by Mr Fraser's death.
The statement added: "Our thoughts are with his family and friends."
It also said Mr Fraser had been offered welfare support during his suspension from the force.
Mr Fraser was due to appear at court in St Albans with his wife, Teresa, also a serving officer, on Monday charged with perverting the course of justice over a speeding incident in Scotland, which was being investigated by Hertfordshire Constabulary.
It is alleged Mrs Fraser, who has been suspended from West Midlands Police pending the outcome of the investigation, accepted responsibility for a speeding offence committed by her husband in Strathclyde last September.
Mr Fraser had been suspended from duty since December 2010, pending a separate investigation being carried out by Merseyside
Police, which confirmed earlier this year it was investigating the officer and three others, including Mrs Fraser, following allegations of misconduct and fraud.
The couple, from Warwickshire, were charged with perverting the course of justice earlier this year after an investigation into the alleged speeding offence.
Speaking after the charges were brought, Baljit Ubhey, chief Crown prosecutor for Thames and Chiltern Crown Prosecution Service, said: "The essence of the charge is that Mr Fraser, having allegedly committed a speeding offence, falsely informed the investigating authorities that Mrs Fraser had been the driver of the vehicle in question, and she falsely accepted responsibility for the speeding offence."
