A French investment manager who put $1.4bn (£1bn) into Bernard Madoff’s fraud-hit scheme has killed himself in his New York office, police said.

Rene-Thierry Magon de la Villehuchet, 65, was found sitting at his desk with both wrists slashed, New York police spokesman Paul Browne said.

A bottle of pills was found near him, but there was no suicide note.

Mr Villehuchet, who was married without children, was co-founder of money manager Access International.
