investigating authority may, in the following circumstance, record, or
cause to be recorded, the deposition, document or deed of a victim of

threat to the victim of an offence, the informant or any
witness, prevent such victim, informant or witness from
appearing before the court or compel him or her to make
statement or deposition contrary to the statement or
document which he or she has made or executed before
the investigating authority, in spite of his or her
appearance in the court,
(b) If such person, informant or witness is, owing to
physical infirmity or being a child, not able to appear
before the police office or government attorney office,

cannot be taken to the court from the place where that
