Rev Yahia Nalou, who has denied the charge, was arrested on 21st August but released later on the same day.
According to Christian Solidarity Worldwide (CSW), the case against the clergyman was brought by a government-backed church committee within SEPC which evicted Rev Nalou from his office in the church building after selling the property to investors. They also obtained a court judgment to evict him from his church-owned home in Omdurman on 13th August, after that property was also sold to investors.
The committee has sold church buildings to local Muslim businessmen against the wishes of the church's governing body.
CSW's Senior Press Officer Kiri Kankhwende said: "CSW is deeply concerned by the criminal case initiated against Reverend Nalou.
"The charges against him are baseless, and are further evidence of the politicisation of the criminal justice process, and the continuing harassment of religious leaders. They should be dropped unconditionally."
Local sources have informed the Christian charity that the arrest of Rev Nalou may have been designed to remove him from the premises in order to allow investors to access and demolish it.
So far, the illegally-convened committee has sold or attempted to sell the Khartoum Bahri Evangelical School, the Evangelical School in Omdurman and several homes used by clergy.
Kankhwende added: "CSW urges the African Union and European Union to remind Sudan of its regional and international obligations to protect freedom of religion or belief.
"The decision to recognise a committee lacking in legitimacy should be reviewed as a matter of urgency; the sales conducted by the committee must be declared invalid, and the monies accrued by it must be returned to the purchasers."
