A dental nurse accused of poisoning her colleagues is in court for a retrial.

Ravinder Kaur, 35, first appeared at Blackfriars Crown Court yesterday (Monday) accused of two counts of administering poison with intent to annoy, injure or aggrieve.

The dental nurse, from Ettrick Drive in Bedford, denies the charge which relates to two separate incidents 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.

The re-trial is expected to last for two weeks.
