Police arrested several men in San Antonio TX for selling fake Justin Bieber tickets the day before the big show with Justin Bieber tickets going at 15 times the face value, authorities say the market is hot for criminals.

Undercover officers arrested the suspect as he tried to sell the same tickets to a different victim. But the officer says it is tough to catch scammers because con artists love to mingle their ads among legitimate sellers .

San Antonio officer said crooks use multiple cell phone numbers and fake IDs to set up the deals.

SAPD officer Matt Porter said:

“Whenever you have a big event like this, you always have that small group of people that are going to try to capitalize on that by scamming the consumer.”
