Irish singer Enya insists the obsessive fans who have followed her and broken into her home need psychological help.

The ORINOCO FLOW hitmaker, recently traumatised when her home was invaded by a fixated fan who tied up her maid, is unsure what causes them to act this way, but thinks they should seek help for their unhealthy behaviour.

She says, "Those kind of people have been there from day one. Regardless of how I live my life, there are people who develop fixations that are not healthy.

"It could be a visual thing, or it could be the music they are drawn to. These people need help."
