TORONTO - Former CBC host Jian Ghomeshi has been found not guilty of sexual assault and choking.

Ontario court Judge William Horkins says the three complainants in the case were simply not credible given their shifting memories and evidence.

Horkins says all he had to go on was the women's credibility, which he said cross-examination showed to be sorely lacking.

Ghomeshi had pleaded not guilty to four counts of sexual assault and one count of overcoming resistance by choking.

The women testified they were being romantic with Ghomeshi when he briefly turned violent in separate incidents in 2002 and 2003.

Ghomeshi's defence argued the witnesses lied during testimony about their interactions with him and so were not credible.
