Exclusive screening revisits one of Wales’ most remarkable police operations

A TWO-PART documentary exploring a major drugs bust that stunned a quiet Pembrokeshire seaside town will have its exclusive English-language premiere in Newport next week.

Cannabis Cove: Operation Seal Bay, produced for S4C, takes viewers back to 1983, when the peace of Newport was shattered by one of the most extraordinary police investigations in Welsh criminal history.

That summer, the town became the unlikely centre of an international smuggling ring after a local fisherman, Andy Burgess, spotted something unusual at a remote beach called Pwll Coch—known locally as Seal Bay.

Soon after, authorities discovered a concealed hatch on nearby Traeth Cell Hywel. Beneath it lay a man-made underground chamber stocked with food, radio equipment and fibreglass resin — “like something straight out of James Bond.”

The mystery unfolds

As detectives began to investigate, residents reported strange activity around Newport — unfamiliar luxury cars on rural lanes, and strangers flashing £50 notes in local pubs.

What followed was a sprawling investigation that reached from Pembrokeshire to Scandinavia and the Middle East. Within days, three men — Robin Boswell, Ken Dewar, and escaped drug trafficker Sam Spanggaard — were arrested.

However, the case soon hit a snag: the drugs had disappeared. Without the contraband, the entire prosecution risked collapse. Detectives began to suspect there was a local connection — someone who knew the coastline well.

Forty years on

More than four decades later, S4C’s new documentary returns to the mystery with rare interviews, archive footage, and dramatic re-enactments.

For the first time, it includes testimony from a local man — known only as “Jim” — whose words are voiced by an actor to protect his identity. “Jim,” who once modified cars for Boswell, became unwittingly entangled in a smuggling network stretching from Pembrokeshire to Morocco and beyond.

The two episodes retrace both the discovery of the secret underground chamber and the international scope of the operation that followed.

Local resident Wendy Phillips recalled: “Everyone knew everyone. Everyone knew each other’s business — that’s just how you were brought up.”

Screening in Newport

The pre-broadcast English-language screening of Cannabis Cove: Operation Seal Bay will take place at 6:30pm on Thursday, November 20, at Canolfan Bethlehem, Upper West Street, Newport.

Following the screening, there will be a Q&A session with retired detectives Don Evans and John Daniels, who worked on the original case, alongside the film’s director James Hale.

Entry is free, but donations will be taken on the door to support Canolfan Bethlehem.

Cannabis Cove: Operation Seal Bay airs on S4C later this month.

A BOAT covered in black plastic sheeting has been removed from the Netpool area of Cardigan as part of a major police investigation into the death of a young woman.

The vessel was taken away at around 11:30pm on Saturday (Nov 15) under police escort and is understood to form a key part of the ongoing forensic inquiry. Officers had cordoned off the slipway near the River Teifi throughout the day, with multiple police vehicles and scenes-of-crime teams attending.

Emergency services were first called to the location around lunchtime on Saturday (Nov 15) following a 999 call, and a large police response was reported soon afterwards.

A man was taken to hospital with serious injuries. His condition has not been confirmed, and Dyfed-Powys Police have not yet said whether any arrests have been made.

The woman, believed to be in her early twenties, has not yet been formally identified.

Police are expected to remain in the area while specialist officers continue their investigation.

The Herald has contacted Dyfed-Powys Police for an official update.

ANGLE lifeboat was launched at 8:56pm on Friday evening (Nov 14) to assist a 15-metre fishing vessel that had suffered mechanical failure around 26.5 miles southwest of St Ann’s Head.

The vessel, with seven crew members aboard, was located just before 11:00pm after the lifeboat made best speed through challenging night-time conditions. Following an assessment by the coxswain, it was decided that, given the vessel’s position, potential hazard to navigation, and the welfare of those on board, the safest option was to take the casualty under tow.

A tow was established and a course set for Milford Docks. After a slow and steady passage lasting more than seven hours, the boats arrived off the port shortly before 7:30am. While waiting for the next lock, the fishing vessel was brought alongside the lifeboat for the final approach.

The casualty was safely secured within Milford Docks by 8:00am. With no further assistance required, Angle’s all-weather lifeboat was refuelled and made ready for service by 8:45am — nearly 12 hours after the initial pager alert.
