Harrow politicians wrote a begging letter to the Chancellor after "yet another" violent incident in the borough.
The latest plea comes after a man was stabbed at a beauty salon in South Harrow on Sunday (October 22).
Harrow West MP Mr Thomas said: "With yet another incident on Northolt Road this weekend, it is vital that the Government start to listen to concerns about crime in Harrow.
"Senior Met Police figures are now saying that some low-level incidents will not be investigated.
"We cannot afford to lose more officers, or see resources diverted to other areas if we are to tackle the rising crime in Harrow.
"We hope by meeting the Chancellor, we can make the case for better funding for the Police across London, which will help keep our community safe."
The Labour Party politicians have written to the Chancellor, Philip Hammond, ahead of the Budget on November 22, requesting a meeting to discuss the potential impact of the planned cuts to the Met Police’s budget.
The Met Police is facing £400 million worth of cuts to their annual budget, despite already making savings of £600 million. These cuts have meant there are 177 fewer police officers and PCSOs in Harrow since 2010.
Other planned measures include the merging of borough command structures to form a tri-borough command, overseeing Brent, Barnet and Harrow – meaning Harrow will no longer have a dedicated Borough Commander.
Harrow has seen violent crime increase recently, with the number of incidents involving a knife rising from 165 in September 2016 to 226 in August, according to Gareth Thomas MP.
Navin Shah, Assembly Member for Harrow and Brent, added: "Like my colleagues, I am concerned about the cuts the Met Police are facing.
"Across London we're seeing police numbers being slashed and crime on the rise.
"It's important we meet with the Chancellor so we can make the case for greater spending on the police.
"The cuts have taken police off our streets reduced the ability to investigate crime. Putting people at risk of crime.
"I am especially concerned that under the current budget there is a black hole for the Met Police.
"This black holes leaves open the possibility of losing another 5,000 police across London."
