Hyndburn's most senior policeman has warned of "unprecedented" challenges with 1,000 police jobs across the county expected to be slashed.
The government is expected to unveil deep cuts to police budgets in its Comprehensive Spending Review later this month.
The Police Federation is predicting up to 40,000 police jobs could be axed across England and Wales, if feared budget cuts of 25 per cent are realised.
Reductions in 24-hour helicopter support and roads and intelligence units have been mooted, along with possible station closures.
And Lancashire Chief Constable Steve Finnigan has admitted the cuts could damage neighbourhood policing.
He said: "There is no doubt that with 1,000 or so fewer people we’re going to be really challenged to continue to deliver the sort of services that we’ve delivered over the last few years.
"I will work really hard to try and minimise any impact on neighbourhood policing. I will not sit here and say that neighbourhood policing - or other important parts of our business - will be untouched."
Hyndburn Chief Superintendent Bob Eastwood said: "We will only receive confirmation of the actual budget cut once the government’s Comprehensive Spending Review is announced in the autumn. With the detail unlikely to be fully available until December it’s hard to say exactly what the impact will be on Accrington.
"However, Lancashire has always been known for high performance and that needs to remain the case as we enter into this period of unprecedented change. We will continue to focus on reducing and detecting crime, anti-social behaviour and on protecting the most vulnerable members of our communities.
"The challenge for us in Accrington and in the Constabulary as a whole is to come through the next few years with a reduced budget and fewer people whilst still delivering high quality policing services to our communities."
