They can apply for an extension.

I cant remember the exact figure, but they can exten up to a few weeks at present without pressing charges.

They can also remove internet access, phone calls and other such devices of a suspect if they can show it is necessary.

I'd also raise the question, if you're going to bring a suspect into a police station, you've pretty much blown the chances of getting evidence on him/her - evidence will dissapear as quickly as his compatriots can make it happen once they realize where he/she has been taken.

Im not at all convinced this request has come from the grass roots of policing and is what the police force really need to beat terrorism.

I feel tackling the severe shortfall in police numbers in most parts of the country and moving away from what appears to be a strategy to take away regional policing by making a smaller number of stations cover a bigger area would be better methods of tackling rising crime.
