A local 28-year-old man has been arrested in connection with the bomb threat that closed South Hook LNG yesterday.
All workers were evacuated from the site yesterday morning, after management received a phone call containing a threat to the site.
After a massive police search the site was declared safe and staff were called back for yesterday's night shift.
Police confirmed that a local man from the Milford Haven area has been arrested as part of the ongoing investigation into the incident.
He is currently in custody at Haverfordwest police station.
Police enquiries are continuing. Anyone with any information is asked to contact Pembrokeshire CID on 0845 330 2000.
The western Telegraph received unconfirmed reports this morning that all workers at the site have downed tools in a protest over yesterday's evacuation procedure.
