Serial killer Peter Tobin was rushed to hospital yesterday after a suspected heart attack, it has been reported.

The 65-year-old, who used to live in Brighton, is serving three life sentences in Edinburgh's Saughton Prison for killing Vicky Hamilton, Dinah McNicol and Angelika Kluk.

Tobin was convicted of murdering 23-year-old Ms Kluk, a Polish student, at a church in Glasgow in 2006.

The following year, the bodies of 18-year-old Ms McNicol, from Essex, and Ms Hamilton, 15, from Redding in Falkirk, were found in the garden of Tobin's former home in Margate, Kent.

Six years ago, police set up a cold case investigation, Operation Anagram, to look at possible links between Tobin and unsolved murders across the UK.

The operation was scaled down last year.
