TOULOUSE, France (AFP)--Drunken French workers, angry that their plant is to be shut down by its U.S. owners, beat up a senior U.S. executive after he visited the factory, the firm alleged Wednesday, an allegation the workers' union denies.

"Forty drunken people verbally and then physically attacked Eric Doesburg as he left the factory" on Tuesday evening, said Molex Inc.'s (MOLX) local boss Marcus Kerriou, adding that Doesburg was both kicked and punched.

But a CGT union official at the plant in Villemur-sur-Tarn in southwestern France said Doesburg, the electronic parts maker's business development chief in the U.S., "did not receive any blows, just eggs."

Doesburg, who currently uses a walking stick after a recent knee operation, went to see a doctor after the incident and made a complaint, said Kerriou.

French Industry Minister Christian Estrosi condemned the alleged attack, saying that "these acts of violence do a disservice to the workers' cause and make negotiations even more difficult."

The Molex workers have been on strike since July 7 to protest against the plan to shut down their factory.
