GARDAÍ WERE CALLED to TV3′s Dublin HQ yesterday as station bosses reacted to the threat of a ‘crazed stalker’, the Irish Sun reports this morning.

Ireland AM presenters Alan Hughes, Mark Cagney and news reader Alan Cantwell were reportedly targeted in a series of menacing phone calls.

And since four gardaí met with station boss Andrew Hanlon in Ballymount at 10.30am yesterday, the phones have been monitored.

The stalker insists he knows the registration numbers of cars the presenters travel in. A station source told the tabloid:

It is very worrying, the station received abusive calls about some presenters in the past. But this man has given car registrations and other sensitive personal info that has got everyone spooked.

He has been ranting and raving and sounds crazy. It appears the caller may have mental problems, so it is being taken very seriously.

And with the station building buzzing ahead of a busy Halloween weekend, the visiting police officers fitted right in. The TV3 worker continued:

Many workers first thought it was a prank when the cops walked into TV3 HQ. There were lots of people in fancy dress around the building for a Halloween-style shoot when the cops were called. So people thought it was part of that.

But after the gardaí walked into the meeting with some of the bosses everyone realised something serious was going on.
