KUALA LUMPUR: Datuk Seri Najib Razak could be detained beyond the period legally permitted if the courts do not clarify whether his SRC International prison sentence has ended, the Attorney-General's Chambers (A-GC) warned today.

The A-GC said an urgent judicial determination was necessary not only to ensure the proper implementation of his conditional royal pardon but also to protect the former prime minister's rights.

"If the court decides that the sentence in the SRC International case has ended, continued detention on the basis of that sentence could result in him being detained beyond the period he should serve.

"Conversely, if the sentence remains in force, its implementation must comply with the terms of the conditional pardon and any relevant court orders," it said in a statement.
