BANGKOK, Sept 1, 2007 (AFP) - A 35-year-old Thai woman was at large with her husband's penis Saturday after discovering the man's unfaithfulness, police said.

Pornbun Sinthusin came home late Friday in Bangkok and found her 34-year-old husband Ploeng Plaekratoke in bed with another woman, said Lieutenant Colonel Kornwat Hunpradit.

Pornbun later gave him several beers before cutting off his penis with "a sharp object," Kornwat said, adding that the husband was in intensive care.

"We suspect she took both her weapon and her husband's penis because we cannot find the penis in their apartment. We even checked a toilet but she did not dump it there," Kornwat said.
