Elderly residents are to be evacuated from their homes after a large wall collapsed in St Davids Hill in Exeter.
A 30 foot section of a wall 20-30 feet high came down onto the pavement and road below at around 8pm.
It is not thought that anyone is trapped beneath the rubble, but the Fire Brigade are using thermal imaging cameras as a precaution.
Due to concerns that further sections of the wall may collapse officers are looking to evacuate approximately 40 elderly and vulnerable residents from 36 flats.
The road remains closed at Iron Bridge, Hele Road and Cowley Road.
