The jury deliberating over a North Canterbury businessman's citizen's arrest case have retired for the evening.
Dave Clemence of Kaiapoi-based family firm Clemence Drilling is accused of kidnapping and assaulting two thieves caught siphoning diesel from his yard.
Clemence accepts he took Matthew Darryl Pender-McLean and Carl Clark to the local police station after catching them stealing fuel from one of his rigs.
But the two complainants say that first he bashed them, tied them up, took them to a river, blindfolded them, and threw them in.
During a week-long trial at Christchurch District Court, Clemence denied using excessive force and ever taking them to a river on the night of April 7, 2011.
