National Police Commissioner Fannie Masemola says while they are pursuing one more suspect in connection with the Lusikisiki mass murders more arrests are not unlikely.
He briefed the media in Parliament yesterday, alongside Police Minister Senzo Mchunu on the latest information available.
Eighteen people were killed in a mass shooting two weeks ago.
Four suspects, among them a parolee, who was handed a life sentence in 2002 for killing a police officer, have been arrested.
All four will appear in court today.
