The two men were abducted by three hooded gunmen on Nov. 9 outside the headquarters of the Heineken brewing company in the center of the city soon after a luncheon Mr. Heineken had given for policemen who foiled an attempt to extort millions from his brewery. Mr. Heineken and Mr. Doderer were taken by panel truck to a west side industrial section, an area of auto wrecking and carpentry shops and other enterprises.

The police had been watching the general area since Nov. 16, when, they said, they received an anonymous telephone tip suggesting that they pay attention to people operating the auto- wrecking and carpentry businesses.

Suspicions that the two men might be held in the area appeared to be confirmed on Sunday, the police said, when one of the suspects ordered two meals to take out at a nearby Chinese restaurant and carried them to the warehouse. The police said they delayed raiding the warehouse out of concern for the men's safety, then decided to move in this morning after the payment of the ransom on Monday had brought no results.

The police said they entered the large warehouse, built like a Quonset hut, at 5:30 A.M. and at first found nothing. Then one of the raiders found evidence of a false wall.

Behind it were two concrete cells, one containing Mr. Heineken and the other Mr. Doderer. The prisoners were handcuffed and tethered to the walls by long chains that allowed them to move about the small cells.
