More than 700 people in the UK have posted on a pro-suicide website looking for someone to die with, a BBC investigation has found.

The site, which we are not naming, has a members-only section where users can look for a suicide partner. We have connected several double suicides to the “partners thread”.

Our investigation also found that predators have used the site to target vulnerable women.

…

We know of two cases where men from the US have travelled to the UK to meet and “assist” vulnerable young women in their plans for suicide.

We are not naming any of those involved at the request of their families.

In one case, a man from Minnesota flew into the UK and stayed in a hotel for more than a week with a 21-year-old woman he had met on the thread.

On the 11th day of sharing a hotel room, the young woman ingested a toxic chemical and died.

The man claimed to have been asleep when she took the substance and called the emergency services when he realised what she had done.

He was arrested and questioned by police but was released without charge and permitted to fly home.
