The Trump National Golf Club in Rancho Palos Verdes is offering a $10,000 reward for information leading to the arrest of the vandals who carved 6-foot-tall letters into grass on the golf course last week.

Sometime between 5 p.m. March 11 and 5:30 a.m. March 12, five people snuck onto the fog-shrouded course and used hand tools to carve the message “NO MORE TIGERS NO MORE WOODS” into the fifth green.

Now the club is offering the five-figure reward for anyone who comes forward with information that will lead to the arrest and conviction of the vandals, according to the Lomita sheriff’s station.

The group recorded the incident, and sent the video to the Washington Post. In a message to the newspaper, the group members called themselves an “anonymous environmental activist collective,” and said the message was in response to the “blatant disregard” for the environment by the administration of President Donald Trump.

The damage to the course was estimated at $20,000, according to Lomita sheriff’s deputies. Previously, Lomita sheriff’s Lt. David Sprengel said chances are slim that any arrests will be made in the case because the video showing the vandals is too dark to make out any of their features.

Anyone with information can call Detective Marcello Curko at 310-891-3244 or Sgt. Ricky Osburn at 310-891-3205.
