A woman from Bedford has appeared at the town's magistrates court accused of poisoning colleagues at a dental practice.
33-year-old Ravinder Kaur is facing two charges of administering poison "with intent to injure, aggrieve or annoy".
It's claimed on March 5 2012 she unlawfully and maliciously administered to Georgia Tobitt a poison, called Mercury Amalgam, with the intent to injure or annoy her, contrary to section 21 of the offences against the person act 1861.
She is charged with committing the same offence against Laura Knowles on 16 March 2012.
Miss Kaur who lives on Ettrick Drive appeared for a couple of minutes only to confirm her name and address.
She was dressed smartly in white blouse and black jacket.
The offences are indictable and can only be heard at a Crown Court.
Miss Kaur was given conditional bail and told that a preliminary hearing will take place on August 14 at Luton Crown Court.
Her bail conditions prohibit her from going to Shefford Medical Centre or contacting Georgia Tobitt, Laura Knowles or any member of staff at the centre.
Mercury Amalgam is traditionally used to produce fillings in the dental industry.
Mercury poisoning, according to its severity, can cause damage to the brain, kidney and lungs.Symptoms include a lack of coordination and impairment of vision, hearing and speech.
