Homeless man Kieran Kelly was convicted in 1984 of killing two people – but has been linked to another 22 murders throughout the 1960s, 70s and 80s.
Geoff Platt, the detective who led the investigation, believes Kelly – who died in prison in 2001 – is responsible for the spate of Tube murders.
Kelly would rank among the worst serial killers to ever stalk the streets of Britain if he did slaughter at least two dozen on the London Underground.

“They’re scared it’s going to happen again”
The murderer possessed a pathological hatred of homosexuals and was a homeless alcoholic when he was arrested.
Kelly was charged with eight murders between 1953 and 1984, but ended up being acquitted of them all.
Mr Platt was a detectie constable with Scotland Yard at the time, and was tasked with looking into Kelly’s alleged killing spree.
The top cop revealed there was an “astonishing” number of times when Kelly was a witness to suspected suicides on Tube lines.
He also claims there was a suspiciously high number of deaths on the Northern Line between Kelly’s stints in prison for Petty crimes.
Mr Platt told The Sun: “He was investigated for 16 murders by me in 1983. We submitted a report to the director of public prosecutions that all 16 were capable of proof, but the instructions came back from the director that we charge for five.”

The cop said: “They’ve already looked at the eight previous cases when they check his criminal record file and in those cases he’s previously admitted them then pleaded not guilty in court.
“They’re scared it’s going to happen again.
“What they don’t want is to have 16 trials. It costs a considerable amount of money – as it turns out those five cases took several months.”
Eventually, authorities were able to convict him of two of the five killings – and he was given a life term.
