A 'vulnerable' British man with advanced Parkinson's disease has gone missing in Paris after becoming separated from his brother when the pair left a restaurant.
Relatives of Chris Arnheim, 65, are increasingly worried about his wellbeing after the tennis fan travelled to Paris to watch the French Open earlier this week.
Accompanied by his brother, Mr Arnheim went for dinner in the Marais district and they were heading back to their accommodation when they became separated on Rue de Turenne.
They had been returning to Rue des Francs-Bourgeois at around 9pm on Thursday when Mr Arnheim went missing.
'We are obviously very concerned about him,' Mr Arnheim's son-in-law Tom told MailOnline.
