BUDAPEST, April 20 (Xinhua) -- Tamas Gyarfas, former persident of the Hungarian Swimming Federation (MUSZ), has been placed in home detention for an incitement to homicide 20 years ago.

Anna Madarasi, the spokeswoman of the Budapest court announced here Friday, "Tamas Gyarfas, has been placed in home detention with a tracking device on Friday in the case of the murder of media entrepreneur Janos Fenyo."

In Hungary, the incitement to homicide is a very difficult crime to prove, and is generally punished by prison sentences of 6 to 13 years.

The detention will be in effect for a period of one month. Gyarfas has made an appeal against the decision.

Gyarfas, who claims innocence and declared the charges as "absurd", had been arrested and interrogated on Wednesday.

He is under suspicion by the National Bureau of Investigation (NNI) for commissioning mobster Tamas Portik some 20 years ago to kill Fenyo, his main rival then.

Besides having been the president of MUSZ from 1993 and 2016, and a current member of the FINA bureau, he has also been the owner of a media enterprise called Nap-TV, which made news programs broadcasted in different channels from the beginning of the 1990s to 2009.

Although Hungarian media reported that "rock-hard evidence, such as voice records" was backing up the case. Gyarfas told that the records were made-up and manipulated.

Fenyo had been murdered with a machine gun in his personal car in Budapest on Feb. 11, 1998.
