South Wales Police are investigating a complaint made by Cardiff City after reports on Sunday that Willie McKay threatened club staff.
The Sunday Telegraph has reported the Premier League club allegedly received threats from McKay - the man who booked the flight that claimed the life of January signing Emiliano Sala.
McKay is alleged to have threatened to "kill everybody" at the club and confronted senior members of staff both in person and over the telephone.
A statement issued to Sky Sports News read: "South Wales Police can confirm that a complaint has been received from Cardiff City Football Club and is currently being investigated."
McKay's son Mark was also involved as an agent in the £15m deal that would have seen Sala join Cardiff.
Sala's body was found in the wreckage of the plane being piloted by David Ibbotson - whose body has yet to be discovered - after it went down in the sea near the Channel Islands on January 21.
The flight was taking Sala to South Wales for what was to be his first training session after finalising a move from French club Nantes,
Earlier this week Cardiff rejected claims they had failed to provide Sala with travel back from France after McKay told the BBC he had been abandoned by the club and forced to make his own arrangements.
Nantes are yet to receive the first payment of the transfer and have made a complaint to FIFA after an extension to the deadline for that instalment also passed.
Cardiff have told Sky Sports News that they "remain committed to ensuring fairness and accountability with respect to the agreement between Cardiff City and FC Nantes, but first and foremost the relevant authorities must be allowed to determine the facts surrounding this tragedy".
