Two people have been arrested on suspicion of assisting the suicide of a disabled man from South Tyneside. Retired engineer Douglas Sinclair, 76, had been suffering from the debilitating disorder multiple system atrophy, his solicitor said. Christopher Potts said Mr Sinclair died in Zurich on 28 July. He arranged his death through the Swiss assisted-suicide organisation Dignitas. The woman and man who were arrested have been bailed as inquiries continue. Mr Sinclair, a father-of-one, had had the condition for two years. He was being cared for at a care home in Jarrow, South Tyneside, when his conditioned worsened earlier this year.
