One of the two teenagers injured in an acid attack in Zanzibar has been discharged from hospital.
Kirstie Trup spent three days at London's Chelsea and Westminster Hospital after being injured in an unprovoked attack on the African island on Wednesday.
A hospital spokeswoman confirmed that Trup had left, while her friend, Katie Gee, was still being treated for burns at the hospital.
"No details on either of the patients' treatment will be released at this time," the spokeswoman said.
"This approach is in line with the families' wishes and we continue to ask that the media respect their privacy at this time."
The pair, both 18 and from north London, were on a volunteering holiday on the island, off the coast of Tanzania, when they were targeted.
A cleric is reported to be in custody after being arrested on suspicion of carrying out the attack.
The UK's Daily Telegraph said sheikh Issa Ponda Issa handed himself in to police a day after he was injured as he tried to evade officers.
Members of both teenagers' families have been keeping a bedside vigil after the pair were flown home and immediately sent to London's regional burns centre.
One friend of the pair told how one of the two men involved in the unprovoked attack "smiled" before throwing acid.
Miss Gee has already thanked well-wishers for their support via Twitter, while a photograph released by the teenagers' families showed the injuries one of them suffered in the attack.
The women were enjoying the last week of a trip as volunteer teachers to the predominantly Muslim island when the corrosive substance was thrown at them in an apparently unprovoked attack.
