The church, owned by Ijaw-born Prophet Jeremiah Omoto-Fufeyin, popularly called “Warri TB Joshua,” is located on the outskirts of Warri.
Tribune Online gathered that the deaths of the trio occurred last weekend at the church’s premises.
The 10-year-old was identified as Emmanuel Odili, who reportedly went to check on his mother who was said to be in the church for prayers.
Sources said Master Odili had earlier been declared missing within the church’s premises by his family members last Friday, but was found floating on Saturday in a ditch dug within the church premises.
His corpse was allegedly recovered by church officials and deposited at a morgue before it was later reported at the Ebrumede Police Station, Effurun in Uvwie Local Government Area of the state.
The two other deaths, as gathered, involved one Mrs Beatrice Nwachukwu, from Imo State, and Antonio Abba, from Kano State.
The duo allegedly gave up the ghost during a deliverance session on Saturday at the church, just as Ebrumede Police Station was said to have been informed.
Meanwhile, a police source from Ebrumede, informed of a controversy trailing what led to the deaths.
The source said while the family of the deceased boy argued that he had no health issue before his death, the church claimed the boy had a mental challenge.
The source, who’s privy to the statements available at the police station, gave further details to the incidents.
According to him, “While the matter of the boy was still being sorted out, people ran down to the police station to report the sudden collapse and death of the woman, Mrs Nwachukwu.
“I later heard that some others later came to report of another death of the man from Kano, one Antonio.
“They said the two died at different intervals on Saturday during prayer sessions.
“They were trying to link Mrs Nwachukwu’s death to a high blood pressure, but her husband claimed nothing was wrong with his wife before they arrived the church.”
Prophet Jeremiah Omoto-Fufeyin, who is the general overseer of the church, could not be reached for comments on the tragedy.
The church’s spokesman, Godday Emiko, when contacted by journalists, denied that such incident occurred at the church.
However, the Delta State Police Command confirmed the development.
The Police Public Relations Officer of the command, Mr Andrew Aniamaka, a DSP, said the command had taken briefs of the development and that investigations were already on.
“Three people actually died; we heard one was through drowning.
“The other two also died in the church. Investigations are ongoing,” Aniamaka told journalists.
