"A notorious sex offender who was banned from possessing orange balloons is back behind bars after admitting breaching a sexual harm prevention order.
David Hunter, 74, of Kettlethorpe Road, Fenton, was arrested following an incident involving two girls on a bus between Lincoln and Boston last year.
He was jailed for three years and nine months for three charges at Lincoln Crown Court on Wednesday.
Hunter was first convicted of taking indecent images in 1994 and has been under a series of orders since 2001.
This was the 36th time Hunter had broken court orders imposed to restrict his activities.
He was previously jailed for three and a half years in December 2017 and prohibited from possessing orange balloons.
Hundreds of photos of girls either holding or blowing-up balloons were found at two properties linked to Hunter in Lincolnshire and Nottinghamshire.
Footage showing Hunter appearing to "simulate sex" with an orange balloon was also seized, the court heard.
Previously, in 2015, Hunter was jailed for three years and four months for filming a girl on a bus and contacting the same child after being released from prison.
He sent a Facebook request to the girl accompanied with a black and white photo of a school boy and references to balloon websites."
