An investigation has been launched after a JCB operator lost control and his machine crashed through barrier and over the harbour wall.

Emergency services were scrambled to Fraserburgh Harbour in Aberdeenshire on Wednesday morning (24/07/2024).
The incident happened at around 7.50am and the excavator was dangling precariously, appearing to be supported only by the bucket arm that was partially submerged in the water.
A man has been taken to hospital for treatment with suspected broken ribs.
Police Scotland have confirmed officers did attend but the matter is being dealt with by the Harbour Board.
A spokesperson for the Scottish Ambulance service said: “We received a call today at 0751 hours to attend an incident in Fraserburgh Harbour.
“We dispatched one ambulance and transferred one male patient to Aberdeen Royal Infirmary.”
A spokeswoman for Fraserburgh Harbour said: “Fraserburgh Harbour can confirm that an incident took place during the morning of 24th July, whereby a small industrial vehicle left the quayside and entered the Harbour.
“The driver, who did not enter the water, was transported to Aberdeen Royal Infirmary for assessment.
“The operation of such vehicles along the quayside does not contravene any Fraserburgh Harbour health and safety guidelines.
“An investigation into the incident is ongoing and the HSE has been notified of the incident.
“It is a requirement for all Harbour users to sign a Contractor & Harbour Users HSEQ Handbook and they are responsible for carrying out a thorough Risk Assessment and Safe Working System HSE assessment of their own activity, and operating with due diligence whilst on Harbour property.”
