'Kill Bill' star David Carradine's manager claims he was murdered in a Thai hotel earlier this week.

The 72-year-old actor was hanging found naked in a cupboard with a curtain rope strung around his neck and genitals on Thursday (04.06.09), and initially believed to have committed suicide.

His manager Chick Binder said, however, his Carradine's hands were tied behind his back and a footprint on the bed in the otherwise immaculate hotel room where he was found did not match his shoes.

Binder said: "For sure there was foul play. We definitely don't believe it was a suicide. David was a great guy and a great client and a great friend."

The actor's lawyer Vicki Roberts said: "I believe there may have been foul play. Anybody could stage a suicide after a murder."

Police in the country's capital, Bangkok, have denied the murder claims, saying CCTV evidence shows nobody came into or went out of the room.

Carradine rose to fame in TV series 'Kung Fu' in the 1970s and went on to star in over 100 films, including 'Mean Streets', 'North and South' and possibly his most famous role as folk singer Woody Guthrie in 'Bound For Glory'. He is survived by his fifth wife, Annie Bierman.
