The incident, which allegedly occurred during a morning gathering, has been described as a “brutal, unprovoked attack”.
The victim sustained a serious facial injury and was admitted to hospital. She was reported to be in a stable condition.
The alleged suspect left the church, but was apprehended by police officers in the car park. The man, who is in his early 30s, was interviewed and arrested late on Sunday.
The police refused to divulge the church at which the attack is said to have taken place.
No plea has been entered.
Meanwhile, Police Commissioner Maara Tetava wants to reassure the public that this type of behaviour will not be tolerated and police will do all they can to come down hard on any violent behaviour.
“These incidents have no place in our community, especially in and around our places of worship.”
