A dental nurse accused of poisoning her work colleagues will not face a third trial.

Ravinder Kaur, 35, was accused of two counts of administering poison with intent to annoy, injure or aggrieve, but the Crown Prosecution Service decided to drop the case in a hearing at Blackfriars Crown Court yesterday afternoon (Monday).

The jury at Blackfriars Crown Court were dismissed after failing to reach a verdict in the retrial on Tuesday, April 8.

The dental nurse, from Ettrick Drive in Bedford, had denied the charges throughout the two trials which related to an incident at Shams Moopen Dental Practice at Shefford Medical Centre in March 2012, when Ms Kaur made coffee.

Female members of staff suffered stomach upsets, alleged to have been caused by dental mercury poisoning.
