Singapore - A Singapore court on Monday sentenced an Australian project manager who threw his Thai wife out of their fourth-floor bedroom window to 25 months in jail, media reports said.

The court found Jason John Porteous, 36, who pleaded guilty to attempted manslaughter, to have been suffering from depression and alcoholism at the time of the May 17 incident.

Porteous was originally accused of attempted murder, but after a psychiatric assessment the charge was lessened.

The Australian was watching television and drinking alcohol when his wife, identified as Ms Pimchaonok, and her cousin, who had been staying with the couple for some weeks, returned home in the evening, the online edition of Straits Times newspaper reported.

As he asked to see the cousin's breasts his wife scolded him for his request.

Later, while his wife was sleeping, Porteous entered the bedroom, picked her up and threw her out of the window.

She managed to grab hold of the window sill but slipped and fell to the ground.

Her cousin found her lying in a drain, bleeding from her head, mouth and ears, but still alive.

Porteous refused to bring his wife to a hospital. Instead, he took a taxi to the airport but returned home and was arrested later, the report said.

His wife was discharged from hospital after several months. (dpa)
