In a statement, Editors' Guild of India President N Ravi said that there ought not to be any attempt to cover up or play down this "extremely serious incident".
"Self-proclaimed atonement and recusal for a period are hardly the remedies for what the allegations show to be outright criminality. The full force of the law must be brought into its investigation and prosecution. Due regard must be paid to the sensitivity and privacy of the victim who has already been put to grievous suffering," it said.
Ravi said that allegations of sexual assault made by the journalist are "on the face of it shocking and shameful."
"Such incidents anywhere are condemnable in the strongest terms but the Guild is particularly saddened that they should engulf a media organisation", he added.
He said that it is emphatically the philosophy of the Guild that the media, that is in the business of holding public persons accountable, should itself be held to the highest standards of conduct and decency.
It also brings out vulnerability of young women journalists who need to be protected and free to pursue their careers without the fear of being subjected to such assaults, it said.
The Delhi Union of Journalists (DUJ) and its Gender and Ethics Councils also strongly condemned the alleged incident.
"Tarun Tejpal's statement admitting a 'lapse of judgement' and his self-declared sabbatical from editorship both confirm the allegation. It is clear that he stands in breach of the law," DUJ said in a statement.
