Stalker Michael Lane was arrested over claims he groomed a 14-year-old girl while volunteering as a Scout leader six years before he murdered Shana Grice, it has emerged.
He was never charged or prosecuted over the 2010 incident but police put a marker on his record, according to a report.
It appears the warning note was not taken into account years later in 2016 when Miss Grice first reported him to Sussex Police for repeatedly stalking and harassing her.
Despite the arrest, Lane was allowed back into the Scouts as a volunteer assistant leader in 2015 when records of his previous membership were missed during his application to re-join, the report said.
The local authority designated officer (LADO), responsible for managing child protection allegations in the area, said Lane should not be barred from his role because the allegations were “unfounded”, the Scouting Association said.
The then 27-year-old was jailed for life with a minimum term of 25 years in 2017 after slitting Miss Grice’s throat near Brighton, East Sussex, on August 25 2016 and trying to set fire to her body.
A domestic homicide review into the 19-year-old’s death revealed Lane’s past connections with police and the concerns raised over his treatment of women more than half a decade before the killing.
