A gas leak at the Grangemouth oil refinery sparked a major response from the emergency services.

Fire, police and ambulance crews were called as part of a multi-agency response to reports of a butane gas leak at the central Scotland terminal shortly after 10am today.

Part of the site was evacuated after the alarm was sounded and road closures were put in place nearby as a precaution.

The emergency response was stood down a short time later and there were no injuries as a result of the incident.

The Scottish Fire and Rescue Service said it sent around eight appliances to the scene - a standard response to such alerts.

A spokeswoman said they were called at 10.09am to a small gas leak in one of the vessels of the oil refinery.

She said: "Ineos have their own fire team there. They took gas readings and phoned us as a precaution but we actually weren't required."

Crews are now away from the scene, the spokeswoman added.

The Scottish Ambulance Service said it had "multiple ambulances" and a special operations response team at the site but they did not have to treat any patients.

Grangemouth operators Ineos confirmed that an "incident" occurred at the site.

"The on-site incident management team were mobilised and managing the incident, which has now been stood down," a company spokesman said.

"As a precaution, we asked the police to close the Bo'ness Road. The road has now reopened."

Police Scotland said the incident was now finished and the road closures have been lifted.

A spokesman said: "Police in Forth Valley Division can confirm that the incident at the Ineos site in Bo'ness Road, Grangemouth, is over.

"A multi-agency response had been initiated following a report of a butane gas leak and temporary road closures had been implemented.

"These have now been removed and the incident passed without any injury or wider risk to the public."
