Mr King was arrested on Thursday morning at his home

A second British man has been arrested on the Costa del Sol in connection with the murders of two Spanish teenagers.

On Thursday, a British barman named by police as Tony Alexander King, 38, was detained in connection with the abduction and murder of 17-year-old Sonia Carabantes last month and the killing of a teenage au pair in 1999.

Spanish news agencies are reporting that Mr King, who has lived in Spain for six years, has admitted to his involvement in both crimes.

The identity of the second man arrested has not been released, but he is reportedly 39 and was arrested in Nerja, southern Spain.

He is suspected of being an accomplice to the murders.

The murder of Miss Carabantes has dominated the Spanish media since she disappeared on 14 August while returning home from a fiesta on the Costa del Sol.

Outrage

Her body was found five days later strangled, beaten and stripped but there was no evidence of sexual assault.

Investigating officers said DNA samples taken from Tony King's home matched DNA recovered in the two cases.

Mr King was apprehended after his girlfriend informed police he had returned home on the morning one of the girls disappeared with bloody clothes and a scratched face.

There were angry scenes on Thursday as crowds gathered near King's home threw missiles and shouted abuse as he was driven away by police.

Rocio Wanninkhof, 19, disappeared from her home in on 9 October, 1999 and was found strangled and left naked but had not been sexually assaulted.

Dolores Vazquez was convicted of the murder and sentenced to 15 years imprisonment.

The prosecution had alleged she murdered Ms Wanninkhof in revenge after a lesbian affair with her mother ended.

Spain's Supreme Court ruled the conviction unsafe and has ordered a retrial.
