An FBI-style website, aimed at tracking the UK's most wanted crime suspects, has received more than 350,000 hits on its first day.
Mr Laurie said technology ensured e-mailers could remain anonymous
The site, launched by Crimestoppers, lists police appeals in the UK as well as pictures of wanted suspects.
The Most Wanted site proved so popular on the morning of its launch, it received 21,000 hits in five minutes.
But many people were unable to access the site, Mick Laurie, chief executive of Crimestoppers, said.
The public will be able to view the photographs, CCTV footage and descriptions of the wanted suspects at www.mostwanted-uk.org and contact police by phone or online.
On Thursday night the site displayed a message which said it could not be accessed because it was still "too busy" as a result of its "unprecedented popularity".
It is the first time police have been able to receive crime tip-offs anonymously online, Crimestoppers says.
People accessing the site will be able to view pictures of the most wanted suspects in their own local communities as well as nationwide appeals.
Crimestoppers' founder Lord Ashcroft said that, as an independent charity, Crimestoppers was in a unique position to receive information from the public that the police would never be able to receive.
"This exciting innovation is something that's been needed for a very long time," he said.
"We believe the Most Wanted website will grow into an essential resource for all police forces.
"With 60% of the population online, we must make sure the public can give information using all possible means of communication."
Detective Superintendent Sean Cunningham of the Metropolitan Police said his officers were helped by the raw information gathered by Crimestoppers.
"They take and process that information into intelligence that we pass to our operational teams and it's those operational teams that go out and save lives..." he said.
"The internet is used for all types of crime. This is one step back toward reclaiming that and making the internet work for us.
"I encourage all forces to log on to the Most Wanted website. The public are the police."
Dave Cording from Crimestoppers said the police would edit the website.
"My concern is the same as everyone else: I don't want trivia on that website and we've had a long process of testing this with a number of key forces."
Mick Laurie said that technology would strip out the details of people e-mailing information to the site so that they could be sure of anonymity.
"These are people who are close to criminals or fear for their safety," he said, at the website's launch.
"We believe this will be a great success."
Nick Ross, presenter of the BBC's Crimewatch programme, hailed it as the "biggest advance since the 'Wanted' poster".
He said: "It is astonishing this has never happened before. Apart from Crimewatch there is virtually no way of getting national publicity for most cases and many wanted people could just disappear - until now.
"Even the police have no effective way of communicating the huge number of wanted suspects."
