Reports of a suspicious vessel sparked a police response at Fishguard Port this morning (Wednesday).
Eyewitnesses told of police, coastguard and Border Force officers at the harbour.
Fishguard Lifeboat launched at 9.48 to escort the vessel to the port.
A RNLI spokesman, said: "The volunteer crew were requested by HM Coastguard to escort a 40ft vessel into the harbour.
"The lifeboat was quickly on scene, as the vessel was in close proximity to the northern breakwater, and escorted the vessel into the harbour and alongside the quay wall and the lifeboat then returned to station at 1030am."
A Dyfed-Powys Police spokesman, said: "Police in Fishguard received a report of a suspicious vessel at the port this morning (September 18).
"The vessel had travelled into the port without initially having permission. Formal permission was later requested and granted.
"Border Force are now in attendance and police have left the scene. Police are content there is no reason for public concern from their initial enquiries.”
