The questions for decision in this case are (1) whether the juvenile witness called by the defendant in fact asserted his privilege against self-incrimination and, if so, (2) whether the trial court’s ruling precluding further examination of this witness was proper. In October 1970 the defendant was convicted after trial by jury of the burglary of a house in Effingham, New Hampshire, on August 12, 1970. Upon the defendant’s exceptions to certain rulings of the superior court, the case was reserved and transferred to this court by the Presiding Justice, Grant, J.
The defendant was convicted on the basis of his written confession and upon other evidence that shortly after the burglary he suddenly came into possession of two of the stolen items, a rifle and a box of ammunition, which he claimed were his own. In his confession the defendant stated that he and “another person” “broke into” the house and took the rifle and ammunition and certain other specified items. At trial, the defendant took the stand and repudiated the confession, asserting that he signed the confession because the officers obtaining the confession indicated to him that *446 only by confessing to the crime would he somehow be able to help his juvenile friend who, he testified, had actually committed the crime.
To corroborate his claim, the defendant called the juvenile as a witness to testify concerning the burglary. The court halted the examination when the witness began to testify as to events surrounding the burglary and appointed counsel to advise the juvenile of his privilege against self-incrimination. The juvenile subsequently testified in chambers that counsel had advised him that “if they were to ask me, ‘Did Bobby Bell go into the house?’ and stuff like that, I was to tell them the truth, that he did.... And if they asked anything about me, that I was to tell them, ‘I refuse to answer on the grounds that it may incriminate me.’” On the basis of this testimony, the court precluded further examination of the juvenile witness in order to protect his privilege against self-incrimination, to which ruling defendant’s trial counsel did not except.
The defendant’s counsel for this appeal asserts that the court erroneously invoked the privilege against self-incrimination on behalf of the witness who alone could properly claim this “personal” privilege. While there may be occasions when an attorney may properly invoke the privilege on behalf of and as agent for his client

v.
United States,
Where it is uncertain -that a witness is actually asserting his privilege against self-incrimination, the trial court should inquire whether he is in fact claiming the privilege. In this case the trial court could reasonably have inferred from the *447 juvenile witness’ statement quoted above that he intended to follow counsel’s advice and claim the privilege. Moreover, defendant’s trial counsel was present in chambers during the examination of the witness and could have urged the court to ask the juvenile if he were actually asserting the privilege, if in fact there had been any real doubt on this question.
It is often said that the privilege against self-incrimination guaranteed by the fifth amendment to the United States Constitution and article 15, part I of the New Hampshire constitution is an option for the witness to refuse to answer each particular question as it is propounded, and not a prohibition of all further inquiry by the examiner.

v.
Harmon,
In the present case, however, it was clear that the only relevant testimony the juvenile witness could give pertained to events occurring during and at the scene of the burglary, such as whether he or the defendant had actually entered the house. The trial court reasoned correctly, contrary to counsel’s advice to the juvenile, that even if the witness were
*448
to state only that the defendant did enter the house, this would tend to incriminate him since the prosecution could then properly inquire on cross-examination into the source of the witness’ information.
State
v.
K.,
In order for the court to dispense with the usual,procedure of requiring the witness to claim his privilege as each question is propounded and instead allow a blanket assertion of the privilege, the court should carefully question the witness as to questions proffered by counsel calling the witness.
See Midgett
v.
State,
*449
We therefore conclude that there was no error. Even if the procedure employed by the trial court had been improper, it would have been harmless error in view of the juvenile’s testimony in chambers that the defendant had indeed entered the house. Some prejudice to the defendant must be established in order to constitute reversible error.

Exceptions overruled.
