Subject: How to use Mathematica find  the solution of an equation when Arg is part of it?


I need to solve the following equation:

Arg[-(I/((1+I \[Omega])^2 \[Omega]))]==-\[Pi]

I have tried Solve (empty output), Reduce (it gives some results but not
the answer Omega=1) and FindRoot (it gives Omega=1 but it is a
numerical search). Is there a way to get the solution not using a
numerical search?

Many thanks


PS. I need to solve several equation of the same kind.
