Terence Healey, an admitted career criminal turned used car dealer, spent almost two years in prison and faced three trials before being acquitted of involvement in an armed robbery. He is seeking damages from Police Commander Latcham whom he says maliciously prosecuted him, using an informer within the robbery gang called Albert Charlton to mount a fabricated case. Latcham says he acted in good faith and that Charlton's evidence was vital to getting dangerous criminals off the streets.
