A man jailed for multiple rapes and deliberately infecting men with HIV, may have had more victims, police are warning.
Adam Hall, 43, from Washington, Tyne and Wear, was sentenced to life in prison, with a minimum term of 23 years, at Newcastle Crown Court on Thursday, where he was convicted in March of raping four men and intentionally passing on the virus to three more.
He is the second person in the UK to be convicted of deliberately transmitting HIV, police said.
Officers believe he has had sexual contact with further men who have yet to be identified, and had travelled to County Durham, Middlesbrough, North Yorkshire, West Yorkshire, Manchester, and London.
After Hall's sentencing Detective Chief Inspector Emma Smith of Northumbria Police said: "We do believe that there are other men who may have been impacted by Adam Hall's behaviour and could be a victim of crime and we would encourage them to come forward."
In a statement, one of Hall's victims said: "No one ever betrayed me the way Hall did. The first time Hall raped me I blamed myself.
"Hall left me a broken man, just a shell of who I was, he stripped me down for his own gain. I am a broken man. He changed me as a person, who I was to my core, and he did it all for his own gain."
Hall was found guilty of a total five counts of rape and seven counts of causing grievous bodily harm with intent through the intentional transmission of HIV.
