A review of a policing pilot for Fulham Broadway and Shepherd's Bush Green has shown violent crime is up by 13 per cent in one ward.
A report on the first 18 months of the £2million pilot praised the performance of police in both wards for achieving their targets, with the exception of violent crime which has seen a rise of 35 offences in Shepherd's Bush.
This is an increase of 13 per cent compared to the same period the year before.
But borough commander detective chief superintendent Kevin Hurley said the rise is due to the extra police deployed since the pilot began in April 2007.
"It's because crime is reported a lot more," he said. "If you have officers on the street, they will come across and detect offences that we class as violent crime.
"If the officers weren't there, they wouldn't come to our notice."
He added that government guidelines mean that officers have to report every crime.
"If someone has a fight with their boyfriend or a friend on the way back from the pub, they won't report it. Police get involved and we will report it. It's a consequence of police presence and intervention," he said.
The report, which will be discussed by Hammersmith and Fulham Council's Local Neighbourhoods Scrutiny Committee on Wednesday adds that there has been a fall in crime across both wards of more than 22 per cent for the 18-month period.
Drugs arrests were up by 76 per cent in Fulham Broadway Ward, with 25 extra arrests.
They were also up by 192 per cent in Shepherd's Bush Green ward with 123 more arrests.
Mr Hurley added: "If you deploy officers in areas of high density on foot in reasonable numbers it will improve the quality of life for those residents, and the figures prove that.
"I know now that it's almost impossible to buy drugs within the Shepherd's Bush area - there's almost no drugs supply going on.
"Street robbery is down by 21 per cent on this time last year and burglary is seven per cent down.
"Hammersmith and Fulham is a lot safer this year than it was last year, and this trend is continuing."
