A man accused of murder told police he was "so, so sorry" after being detained for killing two people, a court has been told.

Robert Stratton, 43, reportedly made the comment during questioning at a Dundee police station in February.

The High Court in Edinburgh heard on Tuesday how DC Nicola Annan recorded Stratton's statement after police held him in custody him over the deaths of Julie McCash, 43, and 32-year-old David Sorrie.

The pair lost their lives after they were stabbed in Dundee's Drumlanrig Drive on February 26.

Stratton turned himself in after telling officers during a telephone call that he had "done something bad".

When questioned, the court was told, Stratton said: "I'm so, so sorry. What the f**k have I done?"

He also claimed to "feel sick," DC Annan added.

Stratton was later formally charged with murdering both Ms McCash and Mr Sorrie.

The 43-year-old denies both murder charges and others including assault and possessing cocaine.

His legal team have lodged special defences of incrimination and claim that he was acting in self defence.

The court earlier heard that the alleged murders took place after a vigil for the friends and family of 18-year-old Ralph Smith, who lost his life after falling from cliffs in Arbroath, Angus the previous day.
