Pleasanton police are investigating a ski boat and trailer fire they believe was caused by arson.
Police officers responded at about 1:15 a.m. Saturday to a report of a boat on fire in the 7800 block of Paseo Santa Cruz. The officers arrived to find a Malibu ski boat and trailer engulfed in flames, as well as a tree at the nearby Pleasanton Tennis and Community Park, police said.
Firefighters extinguished the blaze, and fire investigators determined later Sunday morning that its source was not electrical. Officers searched the area but did not find any possible suspects.
There was no damage to any nearby homes or other structures, and no one was injured in the fire, according to police. Anyone with information about the fire is asked to call Pleasanton police at (925) 931-5100.
