From the BBC report:
A transgender prisoner serving a sentence for murder has been charged with the sexual assault of a fellow inmate at a women's prison.
Alexandra Stewart, previously known as Alan Baker, allegedly attacked the woman at HMP Greenock.
Stewart - a biological male who identifies as a woman – was jailed for the murder of John Weir in 2013 and has been held in a women's unit in the prison since 2016.
Police Scotland said a report would be submitted to the procurator fiscal over the incident.
The Scottish Prison Service (SPS) said it would be inappropriate to comment on ongoing proceedings.
