A pensioner has been arrested over the murder of a woman who was found bound, gagged and drowned in a lake in 1987.

Police are holding a 65-year-old man on suspicion of murdering Lady in the Lake victim Shani Warren, 26.

She vanished 34 years ago after mowing the lawn at her home in Stoke Poges, Bucks, which was bought for her by her parents and she shared with two housemates.

Her body was found face down in Taplow Lake, Bucks, by dog walker Marjorie Arnold after being alerted by her German shepherd pet.

For the first three days after the discovery in April 1987 police treated her death as a suicide.

A murder hunt was only launched after a postmortem, which revealed she had drowned.

Before her body was discovered, a lorry driver saw her car parked in a lay-by on the nearby A4, where he planned to park up for the night. The car had been left unlocked, with one door slightly open.

Some of Shani’s personal belongings were found in the undergrowth near the vehicle, according to a reconstruction on BBC’s Crimewatch.

A coroner recorded an open verdict into her death. Nobody was ever apprehended for her murder.
