Elsie Frost death: Man bailed in girl's 1965 murder inquiry
A man arrested on suspicion of murdering a 14-year-old schoolgirl more than 50 years ago has been bailed.
Elsie Frost was was stabbed to death in a tunnel beneath a railway line in Wakefield on 9 October 1965.
A 78-year-old man - understood to be called Peter Pickering - was arrested in Berkshire on Tuesday but has now been bailed.
The investigation into the teenager's death was re-opened last year after a series of reports on BBC Radio 4.
Det Supt Nick Wallen, of West Yorkshire Police, said the man had been bailed pending further inquiries, adding: "Our investigations into Elsie's murder remain very much ongoing."
Elise was attacked as she walked home from her school's sailing club, close to the River Calder and the Calder and Hebble Canal.
Her body was discovered at the foot of the "ABC" railway service steps by a dog walker.
The latest arrest is only the second since the killing. The first was in 1966 when a 33-year-old man was charged with her murder. The case was thrown out in court after a judge instructed the jury to find him not guilty.
Reacting to the arrest earlier this week, Elsie's younger brother, Colin said: "As a family, we're very pleased. All we wanted was to be taken seriously.
"We were aware that mistakes were made in 1965 but we've been impressed with the commitment of West Yorkshire Police in the reinvestigation - the number of officers involved, the number of agencies involved.
"We wanted the re-investigation to be re-opened and that's what we've achieved."
