The brother of a builder last seen on Monday evening in Dublin has said his sudden disappearance is "completely out of character".

Barry McGinley told Independent.ie that his brother Cathal McGinley was last seen leaving the car park of the Summit Inn in Howth on Monday evening at 9.58pm on CCTV.

Barry says Cathal was driving a blue Ford Focus with the registration number 10 D 2124.

His brother says Cathal contacted his girlfriend, who lives in Cabra, shortly after 10 to say he was on his way home.

He hasn't been seen since.

Cathal is 33 and described as being 6'3", with green eyes, brown hair and a strong build.

When Cathal was last seen he was wearing Sneaker work clothing, cream bottoms but dirty, long sleeved thermal cream/grey & green t-shirt (Jack & Jones), green hoodie and black Nike runners.

He also has a scar on his forehead and his lip.

Barry told Independent.ie that Cathal was born and grew up in Howth so knows the area "like the back of his hand" and that to disappear like this is "completely out of character" for him.

Family and friends have conducted searches for Cathal's car in car parks all over north Dublin but there has been no sign of it so far.
