Balcony death dad jets home.

BALCONY plunge dad John Hogan arrived back in the UK a free man yesterday - less than three years after killing his six-year-old son Liam.

Hogan, 36, was accompanied by a Greek doctor and relatives on the flight from Athens.

He was met by health workers and two police officers at Heathrow airport and taken straight to a psychiatric unit.

Hogan hobbled off BA flight 639 on crutches shortly after 4pm. He refused to answer questions as he was whisked through customs and out a back exit.

It was the first time Hogan has been on British soil since setting off on the tragic family holiday in August 2006.

Hogan snapped and threw his children and himself from a balcony at the Petra Mare Hotel in Crete after rowing with wife Natasha.

Little Liam died in the plunge but Hogan and his daughter Mia, then two, survived.

He was cleared of murder but ordered to have treatment in a Greek psychiatric hospital.
