LOS ANGELES, California ? The son of Bob Arum has been reported missing in the mountains near Seattle forcing the international boxing promoter to abandon a three-city promotional tour to help in the search.

Bob Arum was in Los Angeles Tuesday for the first of three stops on the tour to promote the November 13 Manny Pacquiao and Antonio Margarito junior middleweight title fight.

But Arum left the news conference at the Beverly Hills Hotel early when he learned his son was missing, the Los Angeles Times reported Tuesday night.

John Arum, 49, was apparently hiking in the mountains near Seattle when he went missing.

"We got a call today that he had gone hiking and is missing, so Bob told the staff this morning that he would leave the tour and take a flight to Seattle," boxing promoter Lee Samuels said. "Bob and his wife, Lovee, have left the tour and proceeded to Seattle."

Arum told the Los Angeles Times before leaving for Washington State, "They've got search parties looking for him right now."

The Pacquiao fight will take place at Cowboys Stadium in Dallas. The promotional tour is scheduled to stop in New York Wednesday and then Dallas on Thursday and Friday.

In his last fight, Pacquiao beat Joshua Clottey in Dallas on March 13 in a welterweight bout.
