The call appeals to the public to come forward with any information on the violent crimes following a spate of incidents in the last two months including the fatal shooting of Oliver Tetlow on March 9.
Borough commander Michael Gallagher urged people to stand firm against crime by helping to bring the people responsible to justice.
The senior Brent police officer added that work was underway to boost the number of officers on patrol across the borough.
A total of seven serious crimes have taken place in the two months in Brent most recently including a man who was shot in Grove Way near Wembley Stadium on May 1 ; and a double-shooting a week earlier which saw two men hospitalised.
At a recent safer neighbourhood board meeting, superintendent Gallagher reassured the community and said: “The unprecedented and tragic events in the last two months have brought our policing team, partners and communities together.
"Our teams commitment in bringing those responsible for these crimes to justice and safeguarding the community has never been stronger.
“We are working alongside Trident to further increase patrols in the borough; improve intelligence flow through neighbourhood engagement; and create strong and meaningful conversations with people in classrooms, at street level and in homes and social environments.
“To date the community have been excellent, very forward looking, supportive and challenging. As ever your voice remains a powerful tool in the fight against crime.
“Violence and criminal activity in any form simply has no place in Brent.”
Brent council leader, councillor Muhammed Butt, added: “It is important that the community publicly displays its resilience in the face of the recent incidents of violent crime.
“The community needs to unite against it, come forward with information and send a clear message that crime is not welcome in Brent.”
