POLICE have launched a hunt to find the people responsible for shining laser beams at two Caledonian MacBrayne vessels as they undertook critical docking manoeuvres.

Both attacks took place at Wemyss Bay as the Isle of Bute ferry from Rothesay was going through berthing procedures at dusk on the evenings of Friday and Saturday.

The incidents have been condemned by both Police Scotland and CalMac.

The bridge crews of MVs Argyle and MV Bute were impacted by an intense green laser on both occasions.

The first incident happened around 8.15pm on Friday, when the bridge crew of MV Argyle was dazzled by a beam shone for a prolonged period directly into the bridge. This forced the master to reduce speed further than usually required, though the docking procedure was safely concluded.

The second incident took place 24 hours later when MV Bute was preparing to dock at approximately 8.10pm.

Again, the laser was shone directly into the bridge and while the master and crew were able to avert their eyes it caused considerable distraction at a crucial time – once more, though, the vessel’s crew remained professional throughout and was able to safely bring the vessel alongside.

Police Scotland has been informed and is carrying out enquiries. Clydeport and Belfast Coastguard have also been notified. Neither crew sustained any injuries.

Robbie Drummond of CalMac said: “I cannot emphasise enough how dangerous such utterly irresponsible behaviour is.

“As well as posing an issue of immediate harm to our crews, these actions are illegal and an offence under the Merchant Shipping Act – they also have the potential to jeopardise the safety of passengers on board and, ultimately, the vessels.

“That may be blunt, but it is absolutely a fact and we condemn the actions of this reckless person or persons in the strongest terms.

“I commend our highly experienced crews for dealing with both incidents with consummate professionalism and expertise.”

A spokeswoman for Police Scotland added: "We can confirm that Police Scotland is investigating these incidents, which are utterly reckless. Thankfully, no one was injured during these incidents.

"Those who carry out this type of act should be aware of the danger that they pose."

Anyone who witnessed either or both of these incidents, or who has relevant information should contact Police Scotland on 101.
