A charity director accused of downloading more than 370 child porn images said his daughter's drug-dealing boyfriend was responsible.
Neil William Morgan, 58, of North Road, Ringmer, denies eight specimen charges of making indecent photographs of a child between November 4 and 12, 2001.
Police seized his home computer on November 13, 2001, and he was quizzed at Brighton police station later that day.
Isleworth Crown Court heard extracts of the interview yesterday during which the defendant maintained his innocence.
He told officers: "My wife and I found some (images). I don't know how they came up. We thought there was a code word and it was his surname which I am not going to tell you."
Pressed on the subject, Morgan said: "I owe him nothing. It was Rose-Terry."
He went on to tell them about Raphael Rose-Terry, his daughter's boyfriend who, he said, was a drug dealer and supplied his daughter with drugs.
"It's a long and very sad story," he said.
Raff, as he was known, lived with the family for about six months, leaving the summer before Morgan's arrest.
The defendant said that while there, Raff and his daughter "downloaded huge amounts of music on the computer" and it was after he left that pornographic images were downloaded.
"I didn't know how to stop them," Morgan told child protection officers. "In the end I had to switch the computer off."
He runs Knowles Tooth, an intermediate treatment centre in Langton Lane, Hurstpierpoint.
The trial continues.
