The Chair of the Ejura Committee, Justice George Kingsley Koomson, on Friday, July 9 exercised the discretion to sit in camera with one of the witnesses.
The Court of Appeal judge said the decision comes at the behest of the witness.
The Committee has had its request for an extension of deadline to hear from more witnesses granted on Friday by the Minister of Interior.
However, there was an unusual delay on Friday as witnesses lined up were not ready at 10:00am when the Committee begins daily sitting at the Prempeh Assmebly Hall in Kumasi.
Mother of injured 20-year-old student Louis Ayikpa was present a little over an hour later to give her witness.
Agartha Donyina told the Committee that her son was about to enter a drug store in Ejura on Tuesday, June 29 when he felt a sharp pain in his stomach.
She said she was initially told that her son had died but it was later at the Ejura Government Hospital that a medical officer told her he was alive. Master Louis Ayikpa was later transferred to the Komfo Anokye Teaching Hospital (KATH).
It was after her testimony that Justice Koomson said the next witness had requested an in-camera hearing.
