A mental health patient who has been missing from a care unit in Chichester for more than a day should not be approached by the public, police have warned.
Jason Merriman, 43, is a compulsory patient at The Oaklands Centre for Acute Care in Chichester, West Sussex. He went out on unescorted leave at 12.45pm on Friday and has failed to return, a Sussex Police spokesman said.
Inspector Robert Moore said: "Jason's behaviour may be erratic and irrational due to his mental condition."
Mr Merriman is white, 6ft 2in, broad, with short brown hair. He was last seen wearing a dark blue long-sleeved sweatshirt, green camouflage trousers and black training shoes with white socks.
He has links across the south coast including Chichester, Southampton, and Brighton, and he might visit the Isle of Wight, the spokesman added.
Assisted suicide remains a criminal offence in England and Wales, punishable by up to 14 years in prison, but individual decisions on prosecution are now made on the circumstances in each case.
Guidelines were issued in 2010 by the Director of Public Prosecutions Keir Starmer, QC which clarified the position on assisted suicide.
It was indicated that anyone acting with compassion to help end the life of someone who has decided they cannot go on would be unlikely to face criminal charges.
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."
A 65-year-old woman and a 25-year-old arrested on suspicion of encouraging or assisting a suicide are mother and son.
The pensioner and her son were held after police suspected they were planning to take her husband to the Dignitas clinic in Switzerland to commit suicide, according to Press Association sources.
A 65-year-old woman and a 25-year-old man have been arrested on suspicion of encouraging or assisting a suicide.
Sussex Police confirmed the pair were arrested in the Chichester area and it has been reported that they had planned to accompany a 71-year-old man to Switzerland to end his life.
Police are investigating to see if the man is able to decide to travel himself.
A Sussex Police spokesperson said: “The investigation is looking into what steps, if any, the suspects had made in taking the man out of the country.
“If it is confirmed the man had the mental capacity to make decisions for himself then we would not be able to prevent him travelling.”
