Ion Ciucur pleaded guilty at London's Old Bailey to conspiracy to cause grievous bodily harm (GBH).

The Romanian national, 29, who lives in Gretna Green, Scotland, listened as prosecutor Caroline Carberry KC told the court the offence related to two incidents in July 2019 involving "castration by clamping".

This related to a wide-ranging conspiracy involving up to 29 offences of extreme body modifications on 13 victims, the removal and trade of body parts, and the uploading of videos, allegedly headed by Marius Gustavson.

Two men previously admitted removing other body parts belonging to Gustavson, originally from Norway, who is accused of carrying out castrations and broadcasting the footage on his "eunuch maker" website.

Nurse Nathan Arnold, 48, from South Kensington, London, admitted the partial removal of Gustavson's nipple, stealing anaesthetic from the hospital where he worked and possessing extreme pornography.

Damien Byrnes, 35, from Tottenham, north London, admitted removing Gustavson's penis.

Jacob Crimi-Appleby, 22, from Epsom in Surrey, pleaded guilty to freezing the leg of Gustavson, causing it to have to be amputated.

Gustavson's alleged "right-hand man", Peter Wates, 66, from Croydon in south London, previously pleaded guilty to conspiracy to cause grievous bodily harm between January 1 2016 and January 1 2022.

Wates was alleged to have been involved with nine of the 29 incidents.

Ashley Williams, 31, from Newport, South Wales, admitted removing another man's testicle.
