A pensioner and her 25-year-old son have been released on bail after they were arrested on suspicion of encouraging or assisting a suicide.
A Sussex Police spokesman said: "It is an offence to encourage or assist suicide under the Coroners and Justice Act 2009 and officers are investigating whether any crime has been committed or is likely to be committed if they do not take action."
The South East is the most unaffordable place to live in the UK. Research has revealed that Chichester in West Sussex is the most expensive place to live. Oxford, Guildford and Cambridge are also among the most unaffordable places to buy homes.
The A286 Stockbridge Road is closed both ways. There is queueing traffic after the failure of a level crossing between Canal Wharf and A286 Avenue de Chartres. The level crossing outside Chichester Station is stuck in the down position.
