Can you name this film noir?

[Andy H]

Hello again chaps. I wonder if any of you can help me name this American film?

Film noir style cop story, made 1940 to 1955 I think. Starring Gene Tierney and Dana Andrews(?)really not sure about the stars. The plot is some thing like:Gangster in prison awaiting trial. One man is a witness but too scared to testify and jumps out of the police station window. Meanwhile, another witness - a girl- takes on the identity of her roommate so that she can escape the clutches of the gang. At the end of the film, the police man in charge of the investigation arranges to meet the girl in a busy shop ( a kind of bait) ; a member of the gang is chasing her up the street from shop to shop and is only caught at the last minute.
Many thanks in advance.

That is The Enforcer, but no Tierney and Andrews. Partly remade as Murder Inc. with Peter Falk.

Wow, thanks everyone! This film was shown as part of a 'noir' season on Film 4 I think, and it has stuck with us. We were trying our hardest to recall who starred, but couldn't be sure. I still can't picture Humph in it, but I'm sure you're right. It's only �3+ at Amazon, so I'll order it on Monday. Thanks again.
