Police appeal as man is stabbed in chest on train

Detectives investigating a stabbing on a train have released an image of a woman they believe can help with their inquiries.
The incident took place just after midnight on Tuesday 1 July on the service between Brighton and Haywards Heath.
One man was taken to hospital with non-life-threatening injuries to his chest after being attacked with a broken bottle.
Another man was arrested on suspicion of grievous bodily harm but was later released without charge, while a third was arrested on suspicion of affray.
A British Transport Police spokesperson said onboard footage showed the victim being threatened and attacked with a glass bottle.
They added that anyone who might recognise the woman pictured should get in contact with them.
