Officials at the National Assembly say they will investigate complaints about inappropriate behaviour made against anyone from outside organisations working with or visiting the Assembly.
It follows the results of two surveys into inappropriate behaviour.
The latest, of support staff working for Assembly Members and carried out by the BBC's Wales Live programme found two claims of sexual assault against BBC staff and one against a politician.
Six staff members said they'd experienced bullying or sexual harassment.
An Assembly spokesperson said:
Also this week, a survey by the Commission which runs the Assembly, found that 37 people (including staff, political party workers and AMs) had experience inappropriate behaviour, 32 on multiple occasions. 42 people said they'd witnessed such behaviour.
In response to both surveys, the Assembly spokesperson said they showed that 'much more must be done' to make the Assembly a safe environment for those working there.
BBC Wales has also responded to the results of its survey:
These surveys are the first to look closely at the experiences of those working in or with the Assembly but elsewhere the scale of the problem has already begun to become clear.
Earlier this year a similar survey found that nearly a fifth of staff at Westminster had experienced or witnessed sexual harassment and inappropriate behaviour while a separate Comres survey of MPs staff, commissioned by ITV News, found that 24% agreed sexual harassment is "rife" within the Palace of Westminster.
In the Assembly, moves have been made to develop a new Dignity and Respect Policy but there have been concerns that events surrounding the death of the former minister Carl Sargeant have made it more difficult for people to come forward with complaints.
These surveys offer an opportunity for that to change and put pressure on political parties and those running the Assembly, as well as the media and other organisations which work with it, to confront such difficult matters.
I've asked each of the political parties operating in the Assembly for their response as well as the Welsh Government.
A spokesperson for the Welsh Government said:
The Welsh Liberal Democrats say they back the Assembly's new Dignity and Respect policy but are aware that they need to make changes themselves following a number of cases involving Lib Dem politicians.
A spokesperson said:
Plaid Cymru's leader Leanne Wood has said that all concerned in Welsh politics can -and must- do better.
A spokesperson for the Labour group of Assembly members shared the same level of 'deep concern' and said that Labour AMs and staff will shortly be getting 'Dignity and Respect' training.
A spokesperson for the UKIP Assembly group said:
