The brother of a Thamesmead woman who died during cosmetic surgery at a clinic in Thailand has paid tribute to his "caring and funny" sister.

Joy Williams, aged 23, is said to have been undergoing buttock augmentation by an allegedly uncertified surgeon in Bangkok before her death.

She reportedly died during a corrective procedure on Thursday (October 23) after having the surgery at the same clinic in the Thai capital weeks earlier.

Miss Williams moved to Thamesmead with her mother, Christie, in 2007 and had previously traveled to Thailand "two or three times" before her death.

Her brother, Anietie Willams, aged 28, who lives in Lagos, Nigeria, has paid tribute to his beloved sister, who was due to travel to Lagos in December, saying: "She was a very nice and caring person.

"She brought joy to people's lives.

"She was a beautiful girl, loved by everybody.

"She last came to Nigeria seven years ago - we were looking forward to see her in December.

"We will miss her so much."

Mr Williams said his family did not know Miss Williams had traveled to Thailand last week.

He added: "We don't really know what went wrong, we only know what is in reports in the media.

"My brother will fly to Thailand to try to take her body back to London."

Boonruang Triruangworawat, an official at the Health Service Support Department, said attempts had been made to revive Miss Williams, who stopped breathing after being given an anaesthetic.

Police said the doctor who carried out the operations, named as Sompob Sansiri, was later arrested and, according to the Bankok Post are reporting that he has been charged with negligence.

The clinic has been shut for 60 days while investigations are carried out.

A spokesman for the Foreign Office said: "We were informed of the death of a British national in Thailand on 23 October.

"We stand ready to provide consular assistance."

Consultant plastic surgeon Michael Cadier, president of the British Association of Aesthetic Plastic Surgeons, said: "Details are still emerging, but it's important the public remember the serious risks involved in any surgery, which are increased by travel abroad.

"This tragic case highlights how, if lured by the prospect of what is essentially 'cheap surgery', patients can be left vulnerable.

"It goes to show cosmetic surgery should never be taken lightly and highlights the dangers of travelling to an unknown environment.

"When you go abroad in search of 'cheap cosmetic surgery', you're entrusting your life to individuals whose main concern may be their pocket - not the patient."
