A sex offender spent years secretly spraying young girls in Nottingham with a mixture containing his bodily fluids.
David Long, 75, followed victims around Nottingham city centre before photographing them.
He would then spray the homemade solution on to them and photograph them again, keeping the pictures in journals and scrapbooks.
Police described his behaviour as ‘sickening’ and said “every reasonable step” had been taken to ensure Long had not harmed the health of his victims.
Long, formerly of Forest Road, Loughborough, has now been jailed for six years and eight months after admitting 13 charges of sexually touching three identified children and 10 unidentified children both under and over 13 years of age.
He also admitted making 288 Category B indecent images of children and making 132 Category B pseudo-indecent images of a child.
Long also asked for a further 186 offences of sexually touching females aged under and over 13 to be taken into consideration.
The offences were committed between 2003 and 2016.
After he was arrested police found journals and scrapbooks featuring hundreds of photographs of unidentified children Long had offended against in this way, together with notes containing his sexual fantasies relating to what he had done.
Forensic tests confirmed Long’s DNA was found on victims’ clothing.
Detective Chief Inspector Peter Quinn, of Nottinghamshire Police, said: “Long showed extraordinary levels of perversion and we’re pleased he has been jailed for his sickening acts.
“The investigation was unable to identify every person affected by Long’s actions and there will be people out there who do not know that they have been a victim of his criminality.
“I wish to reassure the public however that every reasonable step has been taken to ensure that Long’s actions have placed no-one’s health at risk and I am satisfied that this is the case.”
