A section of the A30 in West Cornwall has been closed throughout the night after a man climbed a telegraph pole.

Police were called at around 7.15pm last night after concern was raised for the welfare of a man in the area of the A30 at Crowlas.  

The male, believed to be aged in his 30s, was subsequently seen climbing up a telegraph pole next to the A30.

The road was closed at 8.15pm and officers, fire and ambulance services and specially-trained police negotiators attended the scene, along with Western Power workers.

More than 100 homes in the area were without electricity throughout the night after Western Power shut it down as a safety precaution.

The dual carriageway was shut at the junction with the A3074 at St Erth and with the junction of the A394 to Newtown.  

Minor roads in the area are gridlocked this morning as commuters attempt to find alternative routes through Nancledra.

The man remained up the pylon throughout the night. He made his way down at around 7.40am and was taken to hospital at Treliske to be checked over.

The road was reopened by 8.45am.

A 35-year-old man from Penzance has been arrested on suspicion of public nuisance offences.
