Two women have been arrested at Heathrow on suspicion of assisting or encouraging the suicide of a Cardigan woman.
It's believed that 60-year-old Sharon Johnston, who lived in Aberystwyth, travelled to Switzerland with the intention of asking doctors to help end her life.
Sharon was left paralysed after falling down the stairs and was desperate to end her life. She'd become a prominent advocate of assisted dying and remained adamant that it was her right to decide if she wanted to die.
Dyfed Powys Police confirmed a 29-year-old woman from the London area and a 69-year-old woman from Cardiff were arrested after returning to Heathrow Airport and have been released pending further investigation.
Dyfed-Powys Police also confirmed the woman who died is Sharon Johnston, who had been reported missing from her home.
Speaking to WalesOnline last October, Sharon said she intended to travel to Switzerland to end her life because she didn't want to do "a botched suicide".
As a single person with no close family Sharon, who used to run a pub and worked in a bookmaker's, hated relying on others.
"I'm not depressed, I don't feel sorry for myself," Sharon said. "I feel trapped in a body that doesn't work for me. I just want relief and dying is the only way. Life is horrible.
"I'm an outgoing person and I don't want to live this life and it's only going to get harder."
Swiss law enables doctors to assist certain patients to die, although that option is not currently available in the UK. Peers have debated an Assisted Dying Bill in the House of Lords which could change the law.
