A multi-million dollar lawsuit has been launched against Waterloo Regional Police by a well-known Kitchener lawyer.  

CTV reports the suit, launched by Hal Mattson, stems from his arrest two years ago on a charge of obstruction of justice.

A judge later threw the case out.  

Mattson is reportedly seeking over $5,000,000 for, among other things, defamation and punitive damages.

Mattson alleges he was wrongfully arrested, detained and confined.

The suit names the Region of Waterloo, the Police Services Board, the police chief and seven other officers.
