A district nurse was the victim of a robbery on May St, Golborne around 08.30am on Monday 18th November.
She was going about her normal rounds when a male asked her for drugs.
The nurse pointed out that they don't carry drugs and that they are left at the patients home addresses.
The offender then asked for her sharps box which contained dirty needles telling her he had a knife.
A knife was not seen but as the suspect had his right hand in his pocket she rightly feared for her safety and gave the box to him.
She made her way to her nearby car and was followed by the male so she discharged a red spray dye to his face and upper body.
The offender then made off down May St in the direction of Poplar St.
He is described as being a white male, in his thirties, very slim and gaunt looking, with short dark hair.
He was wearing a ribbed black puffer jacket, dirty blue jeans and black trainers.
The dye is difficult to remove so he will have a red face for several days at least.
