Emergency services have been called to a dry dock after a ship partially toppled over.

Police, ambulances and the fire service were called to a report that a ship had become dislodged from its holding at Imperial Dock in Leith at around 8.35am on Wednesday.

Pictures show the Petrel leaning at a 45-degree angle.

The Petrel, a research vessel, was bought and outfitted by the late Microsoft co-founder Paul Allen.

It is not known if anyone has been injured.

The Scottish Ambulance Service sent five ambulances, an air ambulance, three trauma teams and other resources to the scene, while the fire service also attended.

A Police Scotland spokeswoman said: “Officers and emergency service colleagues are responding to an incident at Imperial Dock in Leith, Edinburgh, whereby a ship on dry dock has become dislodged from its holding.

“Police were called to attend at around 8.35am on Wednesday and officers remain at the scene.

“The public are asked to avoid the area to allow emergency service access.”

Leith councillor Adam McVey said the ship became dislodged in strong winds and he described the incident as “terrifying” for those on board.
