Coronation Street star Bill Roache wrote a letter to a 14-year-old after he sexually assaulted her, asking her to reply when she was "back at school," a court has been told.
In evidence, the complainant, now 63-years-old, said Roache forced her to perform a sex act on him in the male toilets at Granada Studios in Manchester in 1965, the Telegraph reported.
She was at the studio to take part in a children's talent show, when she met Roache in the dressing room.
He then pulled her into the nearby toilets.
She said a few weeks later, she received a letter with a signed photograph.
It read: "Dear (the alleged victim), thank you for your marvellous letter and the nice things you said in it.
"I am enclosing a photo which I hope you like.
"I am away for three weeks now but I would like a letter from you waiting for me when I get back.
"Write to me when you start school again and tell me more. Love Bill xx."
The photo was signed "Love to (the alleged victim)!
"William Roache (Ken Barlow)."
The woman said she felt flattered at the attention, but did not fully understand the letter, the Telegraph said.
Prosecutors say Roache took full advantage of his stardom to sexually abuse five young girls.
Roache, 81, denies five historic counts of indecent assault and two historic counts of rape involving the complainants who were aged 16 and under.
