Four men are in police custody while one man is critically ill in hospital after falling from the window of an abandoned office block in Alperton.
Police and emergency services were called to Minavil House, in Ealing Road, at 12.10 am this morning.
A spokesman added: “The man [no further details] was taken to a central London hospital where he remains in a critical condition.
“Four men have been arrested on suspicion of causing grievous harm and remain in custody in a north London police station.”
Minavil House, owned by Lidl, is a part warehouse/ part two storey office building currently sitting empty.
Developer R55 plans to demolish the building and build a 26 storey tower in its place, which has not yet received planning approval.
Police said anyone with any information can call them on 101
