A Leverton driving instructor has been cleared of a second charge of sexually assaulting one of his female pupils.
But the jury at Lincoln Crown Court has now been discharged from reaching any further verdicts in the trial of Keith Warner.
They told the judge they wouldn't be able to agree on any of the other 9 charges of sexual assault.
A decision will be made tomorrow on whether there will be a retrial.
The 61 year old from Outgate has denied all 11 counts - and has now been cleared of two.
