Officers investigating the death of a woman after she was sprayed with a liquid while sitting on a bench in High Wycombe have released a picture of a chemical bottle they are searching for in connection with the incident. 

Joanne Rand, from Marlow, suffered serious burns when a bottle - believed to be an alkaline substance - was kicked during a fight on Frogmoor. 

She sadly died in hospital yesterday. 

Police are urging residents to be on the look out for a white bottle, which may have been discarded in or with a dark coloured shoulder bag.

If anyone sees the bottle - which is white with an orange or red hazard label on the side - they are being asked not to touch it but call police immediately. 

Senior investigating officer Detective Superintendent Paul Hayles, from Buckinghamshire Force CID, said: "A team of detectives is continuing to investigate this incident and carry out enquiries.

"I would like to appeal to the public, particularly those who live or work between Frogmoor and the railway station in High Wycombe, to be aware of the bottle photographed which may have been discarded possibly in or with a dark coloured shoulder bag in the area."
