Hounslow's borough commander has been replaced after being temporarily promoted within the Met Police.
Chief Superintendent Carl Bussey has stepped up to temporarily take over from the West Area Commander, Makhdum Chishty, and will now be helping to fight crime in eight west London boroughs.
The move happened last Monday (February 17), with Superintendent Sally Benatar taking over as the acting borough commander.
She has taken over the job temporarily but due to the Met's promotion system her role as Hounslow's new police chief cannot be set in stone yet.
Mr Bussey said: "I'm pleased to be given the opportunity to oversee policing in West London but I am sad to be leaving Hounslow. I am proud of the excellent performance we have achieved over the past two years to make Hounslow a safer borough, working in partnership with the local authority.
"As West Area Commander I will be responsible for Hounslow together with eight other boroughs so I will maintain a keen interest in policing here."
It is thought Mr Bussey will eventually take over Mr Chishty's role permanently but he will have to be made a commander before the promotion can take place.
Mr Bussey has made swift moves to climb up the Met's ladder. Hounslow was his second borough commander position as he stepped into the role in May 2012 following a stint as Hillingdon's police chief.
In between the two borough commander jobs, he was the acting commander for the Met's Directorate of Professional Standards where he dealt with a number of cases involving disciplining officers.
