‘She reported waking up in what officers later said was Hippodrome House Car Park in the early hours of June 30 with no recollection of what had happened to her,’ a police spokeswoman said.
An investigation was launched, led by Hampshire Constabulary’s specialist Operation Amberstone team, before extensive CCTV enquiries led to the arrest of Booth.
Booth denied the charge of rape but was found guilty by jurors.
He was remanded in custody to appear at the same court on Wednesday September 7 for sentencing.
