Peter Clarke's inquiry was suspended on Monday
Theda Williams, an English teacher at Ysgol Gyfun Rhydfelen in Pontypridd, has been suspended by Rhondda Cynon Taff County Council.
On Monday, the inquiry into the case of former teacher and writer John Owen, which was being carried out by Wales's children's commissioner Peter Clarke, was suspended at the request of the police.
Mr Owen, writer of S4C youth drama Pam Fi Duw? (Why Me, God?), killed himself last year before he was due to stand trial on charges of sexually abusing former pupils.
At the inquiry on Monday, it became apparent that fresh allegations had been made against at least two other people.
South Wales Police had called for the delay so they could follow up new evidence given to Wales's Children's Commissioner Peter Clarke during the inquiry
Mr Owen killed himself last October, the day before he was due to stand trial accused of abusing pupils while teaching at Ysgol Gyfun Rhydfelen in Pontypridd between 1977 and 1991.
Abuse allegations
On Monday the inquiry heard for the first time allegations that Mr Owen abused a female pupil at the school.
The Clywch inquiry, at the University of Glamorgan in Treforest near Cardiff, was due to hear evidence from seven of Owen's alleged victims - five men and two women.
The inquiry is to resume on Friday 3 May but it is unclear whether further evidence will be heard then.
A representative from a teaching union was present at the inquiry on Monday to represent a person " who might be concerned with the inquiry".
But the counsel for the inquiry, Nicholas Cooke QC, stated that this new police investigation did not point to the existence of a paedophile ring at Ysgol Gyfun Rhydfelen where Mr Owen taught drama until he resigned in 1991.
The inquiry into John Owen, from Tylorstown in the Rhondda, is the first inquiry to be held by Peter Clarke, since his appointment in spring 2001.
It follows the Waterhouse report into widespread abuse at children's homes in north Wales.
On its opening in March, he said it was intended to be investigative rather than judgemental, and would not be concerned with civil or criminal liability.
Last year, four of Owen's former pupils came forward with abuse allegations dating back to the 1970s.
He was charged with five counts of indecency with boys between 1974 and 1991.
In October 2001, he failed to appear at Cardiff Crown Court for a pre-trial hearing and a warrant was issued for his arrest.
Committed suicide
The next day he was found dead in a caravan at Trecco Bay, Porthcawl on the south Wales coast.
An inquest at Pontypridd in December heard how Owen killed himself with an overdose of morphine.
Coroner Phillip Walters said he was satisfied it was the abuse allegations which led him to commit suicide.
The hearing is due to continue until June with a report being published by the end of the year.
