We are still in the very early stages of this investigation and our enquiries to understand exactly what happened are ongoing.
I want to reassure people that this is being treated as an isolated incident and we now have a named suspect in custody.
But we are still keen to hear from any witnesses or anyone who may be able to help us piece together the events of yesterday evening.
Perhaps you saw the man drop from the flat or heard a disturbance in the moments before or after he fell; please speak to officers at the scene or give us a call.
As always, if anyone has any concerns whatsoever, they should not hesitate to contact their local neighbourhood team on 101.
