OAKLAND (KRON) — The Golden State Warriors are warning fans about single-game ticket fraud for the second time in the 2015-16 season, according to team spokeswoman Lisa Goodwin.

Goodwin said counterfeit tickets have increased by 45 percent this season. The team warned fans Thursday to be careful when buying tickets from a non-verified third-party.

Fans with counterfeit tickets will not be allowed inside the arena, the team said. The team said in order to make sure your Warriors tickets are valid, you should purchase them at warriors.com or by calling 1-888-GSW-HOOP.

The Warriors have played five games at Oracle Arena this year, including two preseason games and three regular-season games.
