Gardaí have sealed off a site in Dublin over a Coolock man's disappearance.

They're to search an area off the Malahide road tomorrow.

24-year-old Patrick Lawlor has been missing since the 16th of December 2004.

He was last spotted leaving his home in Darndale in Coolock.

Gardaí have sealed off grounds at the now derelict Belcamp House off the Malahide road.

The search will start tomorrow and is expected to last for up to three weeks.

A renewed appeal for info on the Coolock man's disappearance has gone out.

Meanwhile Gardai say yesterday's blaze at Belcamp college isn't linked to the case.
