HOUSTON (AP) — Houston police say as many as 30 fans were scammed by fake tickets for Game 3 of the World Series at Minute Maid Park in Houston.

Police are warning fans to only buy tickets from the venue or trusted vendors for Game 4 of the Astros vs. Los Angeles Dodgers on Saturday night, and Game 5 set for Sunday night.

Investigators didn't immediately provide additional information on the fake tickets to Friday night's game in which the Astros beat the Dodgers 5-3 to take a 2-1 lead in the World Series.

Anyone who bought World Series tickets that turn out to be fraudulent should report the crime to Houston police. An online report can be filed at Houstonpolice.org .
