Ricky Adam
I love night photographs that look like a scene out of a film noir movie. I recently came across Ricky Adam's work on Flickr (website, Flickr). Ricky is an Irish photographer, who seems to shot a lot in northern England. He is currently a staff photographer at Dig BMX Magazine. Ricky's first book 'Urbanite' will be released by Myopic Eye Press. The book is a result of a long term project with photographs taken in various locations around the globe documenting people moving through cities.

There's also some more great night portraits from Leeds here and here and here (the last shot reminds me of Alan Delaney's great book of black-and-white night photographs of London: London After Dark).
