Rolf Harris has been described as a "dirty old man" by his youngest alleged victim, who claims the entertainer molested her when she met him to get an autograph signed at a community centre in Portsmouth between 1968 and 1970.

The woman broke down into tears as she gave her testimony from behind a screen. She said she reached the front of the queue to meet Harris and the TV star touched her inappropriately with his "big hairy hands."

She said: "It didn't matter if it was going to hurt me or not. It felt very aggressive and I knew that it wasn't an accident. There was a moment when I was out of my body and I just wanted to get away."

The woman claimed that although she wanted to scream out and tell Harris to leave her alone, she was too scared, according to BBC News. She admonished Harris in court, describing the artist as a "dirty old man" who assaulted her "out of nowhere".

Harris, 84, denies 12 counts of indecent assault between 1968 and 1986, seven of which pertain to one victim; the childhood friend of his daughter, Bindi. Harris' victims were reportedly aged between 7 or 8 and 19 when the offences are said to have taken place.

Another victim today alleged that she was working as a waitress in Cambridge when she was sent to investigate strange barking noises. She found Harris barking at a dog to entertain a laughing group. The woman's testimony was stopped when a juror reportedly dozed off but she continued to describe the incident that she remembers when she was 13 or 14.

The 'Tie Me Kangaroo Down Sport' singer allegedly put his arm around her and squeezed her bottom several times with a "very firm" grip. "I was too young to understand, but it was basically like groping," she recalled, adding I was completely frozen... I knew it was wrong... I couldn't move... I was extremely embarrassed."

The woman then described the intoxicating melange of emotions that she experienced when Harris, a major celebrity at the time, beckoned her over but then started to grope her. "I just stood there. I couldn't believe what was going on, this famous person putting his arm around me," explained.

"To start it was a very nervous but a good feeling, however his hand then moved and his hand went up and down my back and his hand went over my bottom and it was very firm," the victim added.
