A DENTAL nurse accused of poisoning her colleagues will face a retrial in October.

Ravinder Kaur, 34, a dental nurse working at the Shams Moopen Dental Practice based at Shefford Medical Centre, is accused of two counts of poisoning her colleagues last year.

The charges relate to two separate incidents in March 2012, when Ms Kaur made coffee. Female members of staff suffered stomach upsets, said to have been caused by dental mercury poisoning.

The dental nurse from Ettrick Drive, Bedford, who appeared at Blackfriars Crown Court in London, denied the charge of administering a poison or noxious substance with intent to injure, aggrieve or annoy.

But today (Tuesday) the jury could not reach a verdict and a retrial was announced which will take place on October 28.
