A man has admitted possessing thousands of indecent images of children.
Ian Davison, 60, was found with over 21,500 sick pictures on his computer.
Police also discovered films of children taken from the street.
Davison admitted 23 charges of making and taking indecent images when he appeared at Kirklees Magistrates’ Court.
The offences are so serious that he faces sentencing by a crown court judge.
Linda Fowler, prosecuting said that in 2009 police were made aware of a website where users could access child pornography.
One of the IP addresses was tracked to Davison and his home in Union Road, Liversedge, was searched.
Mrs Fowler said: “His computers were seized and he admitted the downloading of indecent images of children.
“He said he had been looking at adult pornography and started to look at indecent child images.”
The court heard that of the images seized, 421 were graded at the most serious level of five.
A total of 350 movies of children were also found in Davison’s possession.
Mrs Fowler added: “A number of images of children have been filmed from the street by this defendant.”
Davison was committed for sentence at Leeds Crown Court.
He will appear there on August 15 and was granted unconditional bail.
