Emergency services were called to the National Express West Midlands bus garage in Walsall following an accident in the early hours of Saturday morning.
A twenty-four year old man, who works at the garage in Carl Street, Birchills, was reported as fighting for his life after being badly crushed between two buses. He was taken to hospital for treatment.
Paramedics, police and fire crews were called in at around 2.40am.
By the time firefighters arrived, the buses had already been moved, but there is no investigation planned as detectives have stated there is no suspicion of foul play.
The garage is well-known locally as Birchills Bus Depot, and traces its history back to when Walsall Corporation ran public transport from the days of trams to trolley buses.
