A Dublin man has been arrested in Spain as part of an investigation into organised crime there. 

The man, who is in his 30s and from Tallaght, was arrested in Marbella and is being questioned about serious crime including the circumstances surrounding the murder of Gary Hutch.

Gary Hutch was shot dead on the Costa del Sol in September 2015, and was the first victim of an ongoing feud between the Hutch and Kinahan groups, which has so far cost nine lives.

The man in custody is known to gardaí as a senior figure in the Kinahan cartel.
