- Murder suspect on suicide watch moved to secure facility
Dewani, who has denied claims he ordered the killing of his new Swedish-born wife, was transferred to a secure mental health hospital following his behaviour over the weekend.
The argument with a fellow patient was said to have been sparked by an 'adverse reaction' from Dewani to his medication.
Denial: Shrien Dewani insists that he had nothing to do with his wife's death
Police would not say whether Dewani, 31, who is on suicide watch, attacked anyone or was attacked himself.
A source close to him said: 'He had a reaction to his medication, which meant he was loud and noisy.
There was no fight or argument but one female resident got in a heated discussion with him and was taunting him and saying, 'You should go back to South Africa'.'
Dewani has become dishevelled and grim-faced since his stay in the Priory
Fresh-faced: Mr Dewani with his wife Anni who was murdered last November
He gave himself up to police on Sunday and appeared at Bristol Magistrates Court yesterday, where a district judge ruled he should be moved to Cygnet Hospital Kewstoke in Somerset.
Dewani, from Westbury-on-Trym in Bristol, is said to be suffering from severe post-traumatic stress syndrome after the shooting of his wife Anni Dewani, 28, in Cape Town last November.
His symptoms were said to have dramatically worsened last week after he reacted badly to his anti-depressants, culminating in Saturday night's incident.
His psychiatrist, Dr Paul Dedman, said it was likely he suffered an adverse reaction to the medication, according to friends of Dewani.
One said: 'In Shrien's mind he's confused as to what happened (before he surrendered himself to police). He's not certain.'
Set in 16 acres of landscaped grounds overlooking the Bristol Channel, the Cygnet Hospital offers 'a tranquil and therapeutic environment to provide care and treatment for those individuals with complex mental illness'.
Mr Dewani was sent to The Priory Hospital in Bristol for his own safety
His friends said they did not think he would be kept in a secure ward at the hospital but would more likely be staying in its rehabilitation section.
The South African authorities want to extradite him and have made repeated courtroom bids to have him remanded in custody.
But at yesterday's court hearing it was decided his psychiatric healthcare needs would be best met at the Cygnet Hospital, his brother Preyen Dewani said.
His friends said his condition was deteriorating and that he was 'suffering immensely'.
One said: 'We remain concerned for his health and the continued attempts by the South African authorities to smear him and seek his remand in custody.'
The young businessman had been on bail at his home but was last month admitted to the Priory - which specialises in treating mental health problems - after taking an overdose of pills in February.
A psychiatric report by Professor Nigel Eastman, written after the incident, suggested it was 'unlikely he intended to kill himself on this occasion'.
Dewani remains subject to £250,000 bail and strict conditions including a curfew and the requirement that he report daily to a local police station.
Mrs Dewani, from Sweden, was shot when a cab the couple were travelling in on their honeymoon was hijacked in the Gugulethu township.
She was found dead in the back of the abandoned taxi with a bullet wound to her neck after cabbie Zola Tongo drove the newlyweds to the deprived township.
Tongo originally claimed his vehicle was held up and he and Dewani were ejected before Mrs Dewani was driven away and killed.
But in a plea bargain later, Tongo claimed Dewani offered him 15,000 rand (£1,400) to arrange the killing.
The 31-year-old cabbie from Bothasig was sentenced to 18 years in jail for murder, kidnapping, robbery with aggravating circumstances and perverting the course of justice.
Dewani denies arranging a hit on his wife.
