The operations manager of a cleaning firm hanged himself at Heathrow Airport after being told his job was at risk, it has been reported.

Keith Stone, 50, was found hanging from an aircraft de-icing vehicle near Terminal 5, last Wednesday.

The married father-of-three had learned he would have to re-apply for his job following planned cuts at his firm, Aircraft Service International Group (ASIG), The Sun reported.

A source told the newspaper: “Keith was told about the threat to his job two weeks before Christmas.

“He wrestled with anxiety throughout the festive season. The prospect of financial woes proved too much.

“He went to work last Wednesday and emailed his bosses exactly what he thought of them. He then went outside and hanged himself.”

Meanwhile friends and colleagues have been leaving tributes to Mr Stone on Facebook.

Osvaldo Freitas Ramos wrote: "ASIG definitely lost a great man and a great manager. R.I.P Keith."

While Susan Hilsdon added: "I cannot find the words to express my sadness or the sorrow I feel for your family.God Bless Keith, the world is a poorer place without you."

Officers are not treating the death as suspicious.

A Met Police spokesman said: "We were called at 11.10am on January 4th to reports of a deceased man who was found airside at Terminal 5 at Heathrow Airport.

"He was pronounced dead by paramedics at the scene. His death is being treated as non-suspicious and his next-of-kin have been informed."
