A federal jury found former Wackenhut of Hawaii airport security manager Robert Tam Ho not guilty yesterday on all charges stemming from a confrontation with Pacific Wings employees at Kahului Airport four years ago.

The jury found Tam Ho not guilty of two counts of depriving Pacific Wings President James Greg Kahlstorf of his constitutional rights under the color of law when he placed Kahlstorf under citizen's arrest for assault on Oct. 20, 2005, then turned him over to Maui police.

U.S. District Judge Michael Seabright dismissed another deprivation charge involving former Pacific Wings security coordinator William Goshorn during trial.

The jury also found Tam Ho not guilty of five counts of witness tampering.

He was accused of persuading a Wackenhut subordinate to make false statements to police of what happened during the confrontation.
