Six arrests on M5 amid Falmouth immigration investigation

Devon and Cornwall Police have since confirmed the motorway disruption was linked to an investigation that began after reports of a suspicious vessel in Falmouth Harbour.

Police said that six men were arrested on the M5 near the Somerset-Devon border.

A spokesperson for the force said: "We were notified shortly before 8am today following reports of a suspicious vessel in Falmouth Harbour.

"Following a number of enquiries, six men were arrested on the M5 near Tiverton on suspicion of immigration offences. They remain in police custody at this time.

"We are working closely with Border Force and the National Crime Agency (NCA) as enquiries continue."

Traffic on the northbound carriageway of the motorway was brought to a halt for some time between Junction 27 (Tiverton) and Junction 26 (Wellington) on Tuesday morning (November 10), with motorists facing lengthy delays as a police operation unfolded.

The congestion began at around 10.30am in wet and foggy conditions, with traffic cameras showing stationary vehicles and queues stretching back along the route.

Traffic reports from AA initially reported an "obstruction" on the carriageway, with all northbound lanes stopped and delays of around 20 minutes. Wet and foggy conditions added to the difficult driving conditions, with visibility reduced across the area.

The arrests led to significant disruption for motorists using the M5 through Devon and Somerset during the morning rush-hour period.

No further details about the vessel or the identities of those arrested have been released at this stage.

Police enquiries remain ongoing, with delays reported on the motorway at the Somerset and Devon border.

Border Force and the NCA have been approached for comment.
