An inquiry into the death of Croydon singer Kirsty MacColl could be reopened in Mexico following the emergence of new evidence.

The 41-year-old singer died four years ago after she was hit by a speedboat while scuba diving in a national park off the coast of Cozumel island in Mexico. Her sons Jamie and Louis witnessed the accident.

Deckhand Juan Jose Cem Yam was found guilty of culpable homocide and fined £61 by a Mexican court last year.

Now new evidence has come to light which casts doubt over who was driving the boat at the time of the accident.

Private investigators hired by the singer's mother, Jean MacColl, hope the information will lead federal prosecutors to reopen the case.

Ms MacColl, who was born in Croydon, had a string of hits in the 1980s with tracks including a version of the Kinks' single Days.

She was best known for her 1987 Christmas hit with The Pogues, Fairytale of New York, which reached number two in the charts.
