One person has been arrested after a disturbance inside the Penally asylum seeker camp.
A large police presence was seen outside the Pembrokeshire site on Tuesday afternoon.
One person was arrested after the incident involving a “small group” of people.
A spokesperson for Dyfed-Powys Police said: “We were called to a disturbance involving a small group of people within the Penally Asylum Accommodation Centre at around 1.45pm today (Tuesday, 20 October).
“One person has been arrested. The investigation is ongoing.”
The former Welsh training camp in Pembrokeshire was chosen by the Ministry of Defence to house to house around 230 asylum seekers.
But the decision has proved controversial, with dozens of protestors both against and in support of the camp campaigning outside the facility every weekend.
On Friday, Jane Hutt MS, deputy minister and chief whip, called on the camp to be closed and described it as the “direct opposite” to basic equality and human rights needs.
She said: “We can be proud of the way our nation has responded to successive refugee crises, providing a warm welcome and opportunities to integrate with our communities. However, the decision by the Home Office to use the Penally military camp as a centre to house asylum seekers is the direct opposite of the Nation of Sanctuary approach.
“We believe the use of the camp should end as quickly as possible.
“The Welsh Government has repeatedly expressed significant concerns about the suitability of the camp at Penally being used to accommodate asylum seekers.
“The camp does not meet the basic human needs of people seeking a new life in the UK. It places people in accommodation, which is neither designed nor appropriate for long-term use – mainly poorly insulated huts – and risks re-traumatising many vulnerable people who may have been fleeing abuse and torture.
“We sought a delay to the opening of the camp to ensure plans were put in place with local services to enable them to prepare for the arrival of asylum seekers, particularly to make sure Covid-19 public health measures were in place. The Home Office denied this request and, as a result, proper measures have not been put in place.”
