Paramedics treated a man who fell from a multi-storey car park on Salford Quays this morning.
Emergency crews were called to The Lowry Outlet shopping centre at around 8am on Friday.
The man was gravely injured.
Police said he fell “from a height” but were unable to confirm any more details at this stage.
Officers briefly closed off the roads which run around the The Quays.
Diversions are also in place for replacement buses for the closure of the Piccadilly – Eccles Metrolink line.
Due to a police incident at MediaCity the bus replacement service will not call at MediaCity. Please use Broadway instead.
