Vandals caused $40,000 damage to golf equipment and putting greens at the Cedar Crest Country Club in western Fairfax County early Saturday and then stole 48 cases of beer and soda from the club's snack bar, county police reported yesterday.

Police believe a group of about six persons was involved in the vandalism because of the extent of the damage and the fact that the beverages apparently were carried about a half mile to a vehicle parked at the gate of the club, police spokesman Betty Bosarge said.

The vandals apparently entered the golf club, located in a rural of the county of Bull Run Post Office Road by walking through some neighboring woods, police said.

They caused about $30,000 damage to battery chargers, two trucks and 20 golf carts that were parked outside the clubhouse. One gas-powered golf cart is missing, according to police.

The snack bar, was broken into and 33 cases of beer, as well 15 cases of soda and peanuts, potato chips and crackers were stolen.

Damage to the putting greens and flags that mark the course's 18 holes was estimated at $9,000, police said. Hot dogs taken from the snack bar were strewn over the golf course.

Police officer Harold L. Baiden said a policeman had found the front gate locked and nothing unusual during a routine check at the Country Club at about 3 a.m. When club employees arrived at work at 6 a.m. they discovered the vandalism, Baisden said.

Police have requested anyone with information about the incident to call Capt. Robert Ellis at Chantilly District Station at 691-2426.
