The Fiji Women's Rights Movement says a break in at its office in Suva may be a move against the group's position on the 2006 coup.
A digital voice recorder was stolen during the incident two weeks ago. It follows a series of attacks on the homes and cars of six high-profile pro-democracy Fijians during the past few months.
The organisation's Executive Director Virisila Buadromo says it may have been targeted because it's voiced concerns about the country's military regime.
She says whoever took the recorder may see the stored information as a security risk.
"For us we feel it's a form of intimidation. It's a way of telling us who is in power and that we should be quite worried because they've basically invaded a safe space; a space that we work."
Virisila Buadromo says the organisation will now be stepping up its security measures.
