The Trust have confirmed the women, who were from the UK, were on a project for them in the Caribbean island.
The Trust called the incident ‘terrible’, and said the safety of their staff was ‘their greatest concern’.
The women, who are reportedly students aged 31 and 24, are now back in the UK recovering from their ordeal.
Durrell’s statement read: “The Trust can confirm that last week two Durrell representatives were assaulted in the Caribbean whilst working in the field at one of the Trust’s conservation projects.
Durrell works in remote areas that are often in difficult and challenging geographies and terrains. The safety of our staff in the field is our primary concern and as such we do everything we can to mitigate risks.
Our greatest concern is the well being of our staff. The personnel involved in this incident have returned to the UK and are now recovering from their ordeal. We would like to reassure our supporters that we are working with local authorities and are unable to offer further comment at this time.
“We will continue to do all we can to support those affected by this terrible occurrence.”
Seven local men have reportedly been detained after the assault, which took place just before midnight on 10 May.
