London Underground has been fined £500,000 after a maintenance worker was injured in a fall at a disused station.

The worker suffered a number of injuries and spent 10 days in hospital after plunging 9.5 metres from a scaffold tower while cleaning a former lift shaft, the Office of Rail and Road (ORR) said.

Its investigation found London Underground failed to properly plan, manage and supervise the work being carried out on September 22 2014.

Inspectors at disused South Kentish Town Tube station also found the scaffold was incorrectly assembled and its stability had not been assessed.
