Hate crime in the borough has risen, according to the latest figures from police and a hate crime watchdog.
Statistics compiled by the Harrow Hate Crime Forum (HHCF) show from April to June 2008 there were 59 offences committed, an increase of 43 per cent from the same period last year.
It reported a total of 246 racist incidents and 136 racial offences in Harrow over financial 2007-08.
HHCF chair Arpita Dutt, giving a presentation to the borough's Police and Community Consultative Group on Monday, said Marlborough and Edgware were her main concerns.
She told the audience at Harrow Civic Centre: "In Edgware we are not being assisted enough by the agencies involved. Victims still feel unsafe.
"The increase could be because of community confidence in reporting incidents or it might indicate a higher number of incidents.
"My aim is to encourage reporting of race and religious hate crimes; it enables us to get a better picture of what is happening."
The HHCF's yearly figure is taken from police data, Harrow Council's crime reduction figures and information from council-organised reporting sites, where people can drop in to shops and community groups to report concerns confidentially.
Although Harrow police's figures also showed a 31 per cent increase in hate crime from April until June 2008 compared with the same period last year, Mrs Dutt's findings were attacked by a Conservative councillor as "alarmist".
Susan Hall, responsible for community safety in Harrow, said: "I am extremely disappointed - people will think we are living in chaos.
"I don't know where she (Mrs Dutt) is coming from at all. The levels of crime in the borough are low. I found it alarmist."
Harrow's police borough commander also rejected the picture painted by the figures.
Chief Superintendant Richard Walton said: "I completely refute the Harrow Hate Crime Forum.
"We always have challenges of people reporting to us as they do not want to go through court, but we have a very effective unit who deal with these crimes."
In September Harrow Council hosted a launch event to encourage residents to report incidents of hate crime in order to stamp out racism and listen to residents' concerns.
At the time Councillor Chris Mote (Conservative), portfolio holder for community and cultural services, said: "In Harrow we are committed to providing quality of life for every resident.
"We want to encourage people to work with us and our partners to stamp out this despicable behaviour."
