A man caught with more than 370 indecent images of children on his computer blamed his daughter's boyfriend for downloading them, a court heard.
Neil William Morgan, 58, of North Road, Ringmer, Lewes, denies eight specimen charges of making indecent photographs of a child between November 4 and 12 2001.
Andrew Lloyd-Eley, prosecuting, told Isleworth Crown Court that police raided Morgan's home in November 2001 and seized his Mitsubishi Apricot computer.
Of the thousands of images found - not all of which were indecent - there were more than 370 indecent pictures of children under 16, most of them boys.
Mr Lloyd-Eley said: "Examination of the search engine threw up the sites which had been sought through such key words as Dutch boys, young boys, young gay boys, twinks and naked boys.
"Many of the sites entered had lurid and lewd descriptions, such as Schoolboys orgy at summer camp and Virgin schoolboys in XXX box. These are sites that have been deliberately entered.
"The defendant has named his daughter's boyfriend as the probable culprit but that person vehemently denies it and has made a statement to that effect.
"The defendant will further say that he was not at home on the evening of November 12, the night before the police raid. But officers watched his house that night and they saw him at the computer.
"He claims he was at a book fair and that he returned home late. However, the person who drove him home from the book fair says he dropped him near his home much earlier and the defendant has asked him to say it was later."
The trial continues.
